Quickly seal the bag as the chemical reaction between the baking soda and vinegar is about to occur which will result in Carbon Dioxide. This CO2 gas will begin to fill the bag more and more until the bag cannot tolerate being stretched any more and BANG!

Baking Soda and Vinegar Experiment

So how does this simple chemistry experiment for kids work? As baking soda, or sodium bicarbonate, mixes with vinegar, carbon dioxide is created. The bag starts to fill with carbon dioxide (and that’s why you see the bag start to swell up) until the pressure is too much and … BOOM!

  • before you try this easy preschool science experiment ask them to guess what will happen (called a hypothesis)
  • Try with different size bags
  • Or have children mix up the amount of vinegar or baking soda and see what happens
