Rockets

Of course we made film canister rockets as part of learning about fireworks! They're so fun. Some resources:

Also of course, we repeated our ever-popular "building demolition" demonstration where we use strings (not explosives!) to tear down a block creation. It makes me nostalgic to remember how much the big boys loved doing this when they were little. (And this group reminds me so much them, including little Daisy!):
