On Thursday we did a wicked science experiment we made a chemical pop gun. First we got some baking powder and wrapped it in tissue paper, then we put malt vinegar in. We went out side, put the baking soda in the bottle, put a cork in the top and waited for something to happen. After 2 minutes something happened. It all started to foam and the cork started to come off. The cork rocketed right off and flew 24m.
Here, have a look
