lol, does it work ? like them ones that spew out throthy stuff ?
it works, he put baking soda in it then vinegar with red food colouring.
Me and my boy make baking powder rockets and set them off in the back garden - they go quite well.
I found the best mix is to use baking powder with warm water and lemon juice.
Takes a bit of practice to get the mix right. Too much baking powder and the reaction is too slow.
Too much water and nothing happens.
You could try an alca seltzer and coke instead
