Fizz, fizz, zoom! This baking soda experiment boat is easy to build and fun to race. If you’ve ever dropped a fizzy tablet into a cup of water or made a baking soda volcano, you’ve made the same chemical reaction used here. But this time, we’re using that reaction to power a soda bottle boat, for a short distance at least.This is one baking soda experiment that is more fun with more room, so try this one in the bathtub. You can also experiment with the amount of baking soda and vinegar you add.
