Take a film canister (yeah, before this digital stuff there was this plastic stuff called film), you need the clear plastic kind where the lid fits INSIDE the cannister. The gray kind that overlaps the top will not work. Get some dissolving antacid tablets (you know, plop plop, fizz fizz...not tums) and some warm water. Put 1/4 of a tablet in the cannister. Add some water. Quickly put on the lid. The cannister will POP way up in the air. You can leave it right side up or turn it over, it works both ways. My two boys will do this until we run out of tablets. This is an OUTSIDE activity.
Making goop: Take white glue and mix it with liquid laundry starch. The ratio is 2:1. That is, 1/2 cup glue to 1/4 cup starch. Or 1 cup glue to 1/2 cup starch, etc. Add some food coloring if you want. Mix in a bowl. If it is too liquid, add a bit more starch. My two boys, 8 and 10, spent over an hour playing with this stuff the other day. Add some army men or action figures for more fun. Will keep in a plastic zip bag in the frig for a few days. Do not eat.
