This is getting pricey:

Solution A:

• Potassium Iodate $40 (this is for 100g and the video calls for 43g).
  
• Sulfuric acid $20 I don't think this is concentrated enough to do the trick. This might be a showstopper since, even if I could get ahold of a higher concentration, I've heard too many horror stories about working with undiluted sulfuric acid that I may just want to pass.
  
  Solution B:
  
  
• Corn Starch $8
  
• Malonic Acid $10
  
• Manganese Sulfate Monohydrate $15
  
  Solution C:
  
  
• Hydrogen Peroxide $17
  
  
  And distilled water is a couple bucks per gallon at the grocery store. Looking at around $100, and that is assuming I get all the ingredients right the first time and don't have to reorder any of this and ruin some of my ingredients in the process. Many of the ingredients will have leftovers, but the potassium Iodate seems pretty expensive for such a small amount that I'll use half of just to make one batch.
  
  EDIT: Not too surprisingly, it seems like the acids and peroxides I've listed may not be nearly concentrated enough to do the trick.
  
  EDIT2: Updated hydrogen peroxide link to a 35% concentration instead of first aid style which is 2-3%.

I used to create something like this as a kid using zap glue and spraying way too much zip kicker on it. It comes out pure white like styrofoam. Be careful because it is exothermic. Gave myself quite a burn once doing it. Not a scientist and not sure exactly how safe it is. The volume will also be way less than a can of Great Stuff, but maybe an idea?

I don't believe he's made a book of his 'Things I won't work with,' which is a real shame, but he did put together a more serious Chemistry book aimed at teaching the history of the field to non chemists. I bought it after reading his blog posts, and I thought it was well worth a read. Not as focused on humor, but the same good writing.

This looks like the stuff

Same company makes magnetic putty. I ordered some of that a couple months back and it's fun stuff!

We made some of it in the lab a long time ago. People really love playing with it. Though be careful, the stuff is usually very unsafe so keep it sealed. For anyone looking for some:

I have been meaning to buy this for my personal use, I do not know if it is as good as others, but there is the link anyway.

Pretty sure it is, you can buy it on amazon

The same concept is used for backflow incense burners: http://imgur.com/gallery/Lyi4s2S

I got one, and I love it. It is surprisingly cheap too: https://www.amazon.com/Pixnor-Ceramic-Incense-Burner-Backflow/dp/B01LY8KOA4/ref=sr_1_1?s=home-garden&ie=UTF8&qid=1484454274&sr=1-1&keywords=Pixnor+Ceramic+Glaze+Incense+Smoke

If you are into incense, it is something that most people I know haven't seen before. The only major downside is that since the coned incense needs to be hollowed out the incense doesn't last too long.

It isn't exactly only because of the buttons, for sure. But this is a really interesting read if you're into history and science.

No, that was a burst of flame. I'm pretty sure they just tossed sawdust into the fire. For something more impressive, you can get packets of different minerals and salts and stuff, which spark and colorize when lit on fire.

This is Bill Hammock's channel but it's missing a lot of videos. He had a bunch when he worked in some kind of office.

Someone else uploaded a mirror of it. He has some humor in the older ones.

I've looked for the book he references as well--The Measure of Man: Human Factors in Design by Henry Dreyfuss--it's expensive. There is a revised edition if you're actually curious about the measurements.

The appearance of car windows through polarised sunglasses is due to the toughening process during manufacture, in which the hot glass is cooled by jets of air. This causes the outside surface to be in a state of compression and the inner surface to be in tension.

Strains in glass can be seen with polarised light, and using polarised sunglasses shows up the pattern of air jets used in the toughening process.
