Cold air balloon

goal: get the balloon to pop. Test 1: Cold air balloon is a mixture of vinager and baking soda mixed with water then it makes a chemical reaction that makes the balloon blow up and makes the balloon cold. what you'll need: you'll need baking soda a balloon and waterbottle and vinager. the balloon should blow up and stay like that for a long time. the balloon did not pop.

Test 2: We got a milk bottle this time, and put 1 cup and 1/2 of baking soda in the balloon and put 2 and 1/2 cups of vinager then put the balloon on the milk bottle and lift up the balloon to get the baking soda in the balloon then watch the magic happen. 

Test 3: this time we got a one liter pump bottle, we just poured the vinager in the bottle and put heaps of baking soda in the ballon, you will need to get a stronger balloon then the last two times to make the top of the balloon not to brake when you put it on the bottle, also put a bit of tape where the lid goes on the bottle.
the balloon got really big this time but did not pop.
