Solar Energy Balloon Blow Up!

Explore the power of the sun's heat by blowing up a balloon on a bottle! Kids paint one soda bottle white and the other black. Once dry, they attach a small balloon to the necks of their bottles. Then, they put the bottles out in the sun for a solar reaction!

Kids see that the air in the black bottle will make the balloon expand! The white bottle doesn't heat up as fast. Check out the experiment here!
