I built this for about $20 (not including the erlenmeyer and the stir bar).

I got the cigar box a while back at a second hand store.

Here's the USB powered PC fan I used:
http://www.amazon.com/Thermaltake-Mobile-Fan-External-Cooling/dp/B00080G0BK/ref=sr_1_2?ie=UTF8&qid=1381376532&sr=8-2&keywords=usb+pc+fan

I chose a usb fan so that I could power it with an android usb phone charger and not screw around with splicing wires.

Here's the magnets I used (just needed one though):
http://www.amazon.com/gp/product/B00B1M37MY/ref=oh_details_o00_s00_i02?ie=UTF8&psc=1

Aside from that it just took a few odd nuts, washers, and a bit of superglue. I had to bore the hole in top of the cigar box because the box turned out to be a bit too thick (sorry Pepin Garcia!) to get enough attraction between the magnet and the stir bar. I think I might have had better luck with stronger magnets or a different stir bar but oh well.

As someone suggested I first glued a washer to the fan so that I could move the magnet around a but to find the sweet spot where it didn't shake too bad then I glued the washer in place.

I used the long bolts/nuts that came with the fan to attach it to the lid (you can see the bolts in the first picture). Between the top of the fan and the lid I had to add washers to keep the fan from rubbing on the cigar box.

That's pretty much it. The fan has a variable speed control but I get a small vortex on the lowest setting, and higher settings throws the bar off the magnet.

Now I just need to wait for my soda preforms to show up so I can start saving a bit more yeast after I use the stir plate!

I got the idea for using the soda preforms from here:

Well you can't really infuse anything into the dry ice because the industrial systems used to produce it use multistage separation and cooling. You might be able to do a "soak", but what you will get is an outer coating of your liquid that is frozen around the dry ice pieces. Then you could throw these into your drinks and watch the fireworks go off. This will almost certainly have the exact same effect as if you had just thrown in dry ice pieces into the drink, since the coating will dissolve into the liquid faster than being attached to the CO2 gas. But if that's what you want I would break up everything into the sizes you want, throw them into a cooler (the dry ice will be your main source of temperature regulation, so make sure it is well insulated), and let it do its thing. Not sure how long these will last, so it would be best to make them within a couple hours of serving time

If what you are going for is to have the sublimating CO2 carry your flavor compounds into the air, you're going to have to go via a different route. A couple modernist restaurants do this type of thing, where they build a center piece and pour their aromatic liquid over it. This massively changes the perceived flavors (and adds a bit of showmanship to the dinner), since a good portion of taste is dependent on associated smells. Here is the Fat Duck doing it.

If you wanted the drink to carry the smoke, rather than a center piece, then you are going to need some custom glassware. Not sure what your budget is, but you could have something designed and made to suit your needs. If that seems a tad too much, I would build something from existing glassware. Take a normal glass and throw one of these short test tubes on the side, or get some plastic tubing and run it spiraling around the outside of the glass (just depends on your style and what you are going for). After that you can fill up the well with dry ice dust, and when you are ready to present pour in some aromatic liquid. You're going to want to make sure nothing comes out while your guests are drinking from their glass, so I would recommend a stopper of some sort that you have heavily perforated or something porous like a piece of sponge that you have cut to the right shape.

Not sure if this answers your question, but I tried to cover all possible bases. Best of luck with your cocktails!

u/SUICUNE_FUCKER · 1 pointr/ants

I got 60 when I bought mine and I'm currently using about half those. Buying in bulk tends to be cheaper over time as well. The ones I carry on me as "just in case" tubes haven't gotten pretty cloudy due to scratches and oxidation and a few have even cracked a bit just from being carried around constantly. I think I've managed to straight up lose two of them to top if all off. Not a terrible investment and they can be used for other things as well.

Here is what I'd probably get in your case OP. I'd soak them in soapy water and thoroughly wash them out first before I'd use them. This one is pretty good as well if you're not looking for any large species like camponotus. Down side to these would be they're a little small in terms of diameter so they wont really plug and play with most formicariums you can buy.

Personally I'd go with the first option. Its pretty proven and the smaller tubes will probably run out of water quicker. Oh, and its a lot easier to get queens into a larger test tube. I really need to get some larger containers for captures.

u/strikt9 · 5 pointsr/CampingGear

Bottle preforms are great small tubes for keeping things dry

https://www.amazon.com/Soda-Bottle-Preforms-Caps-30/dp/B008MB1QNY

For a while you could buy redbull shots. They were a great small container as well

edit:correcting formatting.
Edit 2: always put rolls of tape in a baggy. When theyre hot they can ooze adhesive and make your kit a mess

u/Stinky_Fartface · 2 pointsr/Homebrewing

I do a similar thing, but these are the tubes I use. I bought two sets of them several years ago and they still work great. I replace the caps every so often. For the rack, I just keep them in six pack holders and put them in the keezer. I fill the unused vials with StarSan solution and store them that way.

I'd also like to add that, after I have racked a new beer into the fermentor, I pour the leftover trub into a mason jar, and then let it sit in the fridge for a day. Usually the trub separates to the bottom leaving a fair bit of usable wort. I give it another quick boil just to make sure its sterile and then make a small starter of something. After pouring off much of the beer, I can usually get about 10 vials of slurry.

u/baconbabe456 · 2 pointsr/weddingplanning

I am struggling with this too, so I will take notes from this thread (thank you).

What I am doing thus far:

tampon flasks because I found them online and thought they were hilarious, and my girls are similarly natured

A mini bottle of her favorite alcohol for each lady (they are all of age)

Custom compact mirrors that I found on etsy; I can customize one for each gal based on her interests (one is getting a disney themed, one is getting PSU, etc)

A necklace to wear for the wedding (so technically not a gift, but they are beautiful so hopefully they will like them anyhow)

Also providing mani/pedi the day before (well my MIL is gifting this to us, so SHE is providing that), hair and makeup for the service, and getting ready food (breakfast and lunch).

As far as other gift ideas though, I am completely clueless. I wanted to make little gift boxes or wedding survival kits for each of them, but I dunno yet.

u/MachinatioVitae · 7 pointsr/Survival

Hey, thanks! Yes, that's the one I was thinking of. I just couldn't find it. Idk about better though. They're different for sure, but they're both made from bottle preforms, so the tube strength should be the same.

The pocket reel comes with:

  • 1 pocket reel
  • 4 fishing hooks
  • 4 removable sinkers
  • 2 metal spinner lures
  • 3/4" bobber
  • knot guide with directions
  • 45' spool of fishing line

    The one I linked comes with:

  • 1 Heavy duty plastic tube with screw top lid.
  • 24’ of 20# monfilament fishing line
  • 3 #2 Eagle Claw Hooks
  • 3 #4 Eagle Claw Hooks
  • 4 #3 Split Shot Lead Sinkers
  • 4 #7 Split Shot Lead Sinkers
  • 2 Slip Bobbers
  • 2 Attached Bobbers
  • 2 Various colored Jigs

    So, with the pocket reel, you get 4 hooks instead of 6, 1 bobber instead of 2, 4 sinkers instead of 8, metal spinners instead of jigs, but almost twice as much line and a "knot guide".

    Seems like about a wash to me. I should note that I don't have a horse in this race, I've never used either and am not affiliated with either shop. The kit I posted was one I found a month or so ago while looking for the one you posted.

    Personally, I went with neither and just bought some bottle preforms for about a buck a piece, filled a couple with the fishing gear I already had and used the rest for other camping gear: spices/oil for cooking, match case, pill bottles, tinder case, etc.
u/Chernoobyl · 2 pointsr/StonerEngineering

Bought some plastic vials off Amazon, fit perfect in my bong. I used an exacto knife that I heated with a lighter to cut into the plastic. Made a few different patterns, the wrap around one works really good, gives a nice clean pull.

u/Harbingerx81 · 6 pointsr/electronics

I only found one older post similar to this from months ago, so sorry if something like this was posted recently and I missed it.

Finally got around to getting my SMD components organized in a useful and convenient way...All of my small sectional storage boxes were getting full and those things get expensive/take up way too much space...I was also annoyed at needing to keep components stored in their sections of tape to keep them from slipping through cracks into other sections...The obvious solution: Test tubes! Compact, easy to label and move around, easy to dispense from and very cheap!

Now, these are what I ordered:

https://www.amazon.com/gp/product/B00CSWFMOC/

A word of caution however...There is a reason I left gaps between the sections...While it is supposed to be a set of 90 tubes and caps, I only received 87 tubes and about 77 caps...Reading the reviews, it seems this is common...For ~$17 though I am not terribly upset and not going to bother trying to get it corrected.

u/andersonmatt1125 · 1 pointr/Homebrewing

Here's a link to those tubes. They're pretty common, you might be able to find a better price than that.

They're food-grade (obviously) so they supposedly work well. Haven't used them myself though. These should only be used for starters though. After storage you're likely not going to have enough viability in a single vial for a healthy pitch.

u/UHElle · 4 pointsr/TakeaPlantLeaveaPlant

If you’re looking for a specific product, I’ve purchased a couple packages of borosilicate test tubes that work super well and would work wonderfully in this.

I have 2 packs of these.

u/TexasHex · 2 pointsr/DIY_eJuice

See if you can find something like these and this. The test tube rack fits on my scale just fine. I use the 8 ml tubes but they go much higher. Be sure to match up the diameter of the rack holes and tubes. Inexpensive, reusable , quick and efficient.

u/esseffgee · 2 pointsr/CampingandHiking

Oh wow, I'll have to give these a go. I've been using a few of the Nalgene Travel Bottle Kit bottles for olive oil, hot sauce, etc, and soda bottle pre-forms for batteries and some other stuff. But they're too big for most things like seasoning/spices, and not big enough for stuff like pancake mix.

u/Davec433 · 3 pointsr/Homebrewing

Short answer if you just freeze yeast the freezing water solidifies and punctures cell wells, killing most of the yeast.

Long answer if you add a 50/50 solution of (water or beer) with food grade glycerin the water will get cold but never freeze.

My process:

Harvest yeast- overbuilding a starter is the easiest way or you could harvest and wash your yeast.

Decant Beer from your starter or use water and half fill a 1 pt mason jar and top off the rest with food grade glycerin. Boiling at this point is probably unnecessary but I do it anyway just to make sure no bugs get transferred in. Cool.

I then spray everything I use with Starsan and then dip everything I’m using in to the boiling water.

I use Soda Preforms but will switch to 1.5 ounce glasses once I burn through my preforms because I can boil them killing anything and not have to worry about melting plastic plus they’re cheaper.

I fill them halfway with my Decanted Yeast Slurry and let it settle. You want the settled yeast to be about half of the Preform which is approximately 100 billion cells. I then Decant excess liquid off and top off with your 50/50 (Water or starter beer) and glycerin.

Cap/Label place in an insulated bag with an ice pack to protect from freezing/thaw cycles and place in the freezer.

u/number3737355 · 1 pointr/PlantedTank

You can also buy in bulk but its also worth it with the api liquid kit, on amazon some water transfer pippets and test tubes to make things easier with many tests at once.

u/katerkline · 2 pointsr/vaporents

I got one off of amazon. Here’s the link The fit is a bit loose, but it’s manageable. I love mine and use it daily.

u/grande_o · 1 pointr/arduino

For rest stir storage I just moved all of mine into plastic test tubes this weekend. It took me a few hours to separate them from the paper strips, label the tubes, and out all the resistors into them but it was totally worth it. They were $10 from Amazon (Hicarer 50 Pieces Clear Plastic Test Tubes 12 by 75 mm with Push Caps, 5 ml https://www.amazon.com/dp/B074V7T8HJ/ref=cm_sw_r_cp_api_F6ZZAbFE5GYX9)

u/savage4618 · 1 pointr/geocaching

THESE are cheaper and more durable/waterproof. A little bit of spray paint or camo tape and it blends in just as well as the other mentioned containers. In my area we have a lot of waterways and these make GREAT paddle caches.

u/roboto6 · 2 pointsr/bettafish

I got these. I use a 5ml syringe (like what you use to dose kids liquid meds) to measure out water from my tanks into those test tubes.

My only tip would be, the lids can be a bit fussy, make sure the top inside liner is flush to the top (poke it down if it isn't) and they'll screw on better.

u/Maeby78 · 2 pointsr/funny

These fit nicely in your purse, and security never messes with them too closely.

u/keirx · 4 pointsr/fountainpens

You can buy vials from Amazon or [Goulet] (https://www.gouletpens.com/goulet-empty-ink-sample-vials/p/GP-10006). And you can get blunt syringes from [Amazon] (https://www.amazon.com/Duda-Energy-Syringepk001-Industrial-Syringes/dp/B00NDETMR2/ref=sr_1_4?ie=UTF8&qid=1485633133&sr=8-4&keywords=blunt+syringe) or Goulet as well. You can also use any small glass or plastic vial you might have, I recommend small spice or jewelry jars. You can often find them in craft shops if that's easier and more local for you. Blunt syringes aren't as easy to find in person, but you can often find wood glue syringes like this in any local woodworking or craft shops.

u/Kush420coma · 3 pointsr/trees
  1. http://www.amazon.com/gp/aw/d/B00CLBWRCA?pc_redir=1407856945&robot_redir=1 It's a tube where you pour alcohol in it and put it in a faux tampon wrapper so you can sneak it around. In my case, I've used it to put my blunts in it for my boyfriend and I for Mad Decent Block Party this Saturday. (Currently on a t-break, excited to smoke again in a couple of days!)

  2. Yes! I love that picture. I bought it from Salvation Army a couple years back. I use it as my blunt rolling station.
u/Reinheitsgebot43 · 2 pointsr/Homebrewing

I’ve been freezing yeast for a couple years. The process in that link is a lot more complicated then it needs to be.

I use a variation of this process.

  1. Build a 2L starter like normal.
  2. Once Fermentation is complete cold crash and decant.
  3. Fill 3/4 of a preform, lightly screw on the cap and place in the fridge.
  4. Revisit the next day and decant till you have 1/2 filled with compacted yeast.
  5. Top off with 1/2 Beer, 1/2 food grade glycerin.
  6. Screw on lid, label, shake and place in freezer.

    Tips
    You’ll want to be as sanitary as possible.
    I can reliably fill 4 soda preforms.
    I’d recommend one have a different color cap to let you know you’re almost out of that particular yeast strain.
    I keep the beer/glycerin mixture in a mason jar and bring it to a boil from time to time since you won’t use as much of it as you’d expect.
    Save used preforms to re-use.
    Only do this for yeast you’ll use or have a hard time getting ahold of. You’re not saving money by saving yeast you’ll never use.
    If I plan on reusing yeast within 6 months I’ll wash the yeast and place in a mason jar.
    In my experience it takes the yeast a day or two longer to wake up once pitched into a starter. Make sure you build that time into your brew schedule.
u/taydaygrim · 3 pointsr/vulvodynia

I bought them straight from my PT so unfortunately I don’t have a link but here are similar to what I have! The important part is the rounded bottom- it also depends on how large you can fit. These are slightly larger than my middle finger for reference.

u/Nyxian · 9 pointsr/trailmeals

Salt & pepper covers me most of the time. Occasionally I'll want olive oil. I use small plastic test tubes with screw lids. They are 5.08 grams and 10 cents each, and hold 15ml. For reference, that would be about 140 calories of olive oil.

The amazon link says 10ml, however a quick water test shows them holding 15-16ml.

They are strong and durable, and resistant to being crushed. Also really useful for medicine or other things you might need to bring along.

u/AlGreat · 1 pointr/trees

Or you can buy some test tubes from amazon pretty cheap and use that since it has an air tight cap.

They are soda bottle preforms (or "baby soda bottles,) which are uninflated 2 liter soda bottles. Available here and on Amazon, and other places.

Doing some sort of shot into these might be appropriate. They're cheap enough and a bit of gold paint from craft store might be enough to glam it up.

They are actually made for soda bottle production. You can usually find big packs for cheap.

These are 60c per vial, but I'm guessing that the ink retailers get them for much less.

For any fam that wants this, Amazon's gotchu!

EDIT: They're actually a bit cheaper at Educational Innovations, its the second link when searching for where to buy unformed soda bottle.

When I first started harvesting yeast my thought was to use what it come in, Test Tubes

Or just stick some of these in your girlfriend's purse.

Assuming your pints are partially filled with spent wort, you can siphon that off and just fill old White Labs tubes with the yeast. If you don't have any old tubes kicking around you can just grab some of these

Just buy some if you like them... https://www.amazon.com/Soda-Bottle-Preforms-Caps-30/dp/B008MB1QNY/ref=sr_1_1?ie=UTF8&qid=1487440522&sr=8-1&keywords=soda+preform

I run a homebrew store and absolutely hate the damn vials. Bags are much easier to keep track of, arrange and take less space.

Are you looking for just the pouch or a complete kit? Bumps and bruises or blowout kit?

I don't run it on the outside of my bag, but my EDC medical setup is a CAT, Israeli bandage, trauma shears, and some everyday meds (IB, benadryl, etc) in a crush-proof tube shoved into an M16 magazine pouch.

Hell, they even make fake tampons designed to sneak alcohol into venues in. It's totally possible.
