What Is THe SCience Behind This exploding bag experiment?

Well, you’re mixing chemicals and seeing the chemical reaction between the baking soda pouch and vinegar. The drops of food coloring just makes it more exciting. But why are the bags exploding?

Well, during the chemical reaction you are mixing a base (baking soda) and vinegar (an acid). And when you mix these ingredients the baking soda is transformed into water and carbon dioxide. And since the bags are closed, the carbon dioxide gas builds up causing it to explode. Once it explodes the gasses and foam is then released. So you want a space with a lot of room, because it’s gonna get messy!

exploding bag experiment Safety Gear

This isn’t a particularly dangerous experiment, but it’s good to instill safety when doing science experiments. Some safety gear for kids (or little scientist in this case) would be:

  • Goggles
  • Gloves
  • Apron

We are all about a fun science experiment, but we are also all about being safe. A cup of vinegar is safe enough that it probably won’t hurt you if you touch it, but accidents happen. We don’t want it in eyes or anything.
