Jin, Mei and Li have great fun learning simple science in this easy and amusing experiment! It only needs vinegar, baking soda, an empty bottle, a balloon and YOU!!! Jump in and have fun learning!!! A note for adults! The vinegar used has to be 12 times that of the baking soda to see good results! So if you use 120mls of vinegar use 10g of baking soda.
