Well, this one should have been online last week, obviously. But despite being a bit late, this movie should still be fun anyway. It deals with the chemistry behind the most american of all American holidays – Thanksgiving.
Some of it is of course somewhat alien to us Europeans, but it translates well: Even if I personally never encountered this particular pop-up-timer, I appreciate the ingenuity of the principle. Also, most of the experiments can be replicated at home, to the enjoyment of your little siblings. Bonus points if you can get your whole family to eat mashed paper towels. Have fun!
