Hot or Cold?


In this exciting experiment, we will see and feel the effects of exothermic (hot) and endothermic (cold) reactions that you can create at home! We will look at how the type of reaction makes a big difference on whether it gets hotter or cooler, and the interesting effects of this scientific principle.

Materials Needed:

  • White vinegar
  • Baking soda
  • Steel wool
  • Ziplock bags
  • Glass jar with lid
  • Thermometer (optional)
