science

today in science we were learning about fizzing chemicals eg baking soda,vinegar and dish washing liquid
this work shows me,Nate,Fletcher and Joesph doing a experiment with a bottle the bottle had water in it the balloon had citric acid and baking soda in it.We had to put the balloon tightly on the bottle so it stayed on when we had done that we then tipped up the balloon and then all of the chemicals went into the water.Then when u put it in the chemicals started to react to the water and started blowing up the balloon.
my next question i would ask is....how do you get the right materials to do the technical experiments.
