She has posted a video of my brother John playing with mentos and diet coke.
Perhaps if we get lucky, my brother will pull out his potato gun and we'll get some footage of that.
With my brother we hacked together some 200$ pens and I took him along to a python user group. My wife thought the $2 pen felt better than the upgraded version, though I disagree with her....
Given that the potato gun is no more, should we build a new one, or make a
big water rocket? I'm wondering if there is a way to combine the mentos
stuff with a water rocket...
But don't you want to make Paul a marshmellow gun? Get him
started on the small stuff, before he turns into a pyromaniac at the age of
3....
