How to make Science/ Discovery Bottles
Calm Down Spot? Rain Bottle -fill a dry empty bottle with a box of toothpicks. Add rice (uncooked) to the bottle leaving an empty space of about 1 1/2 inches at the top. Seal the lid. As you gently turn the bottle, the rice falls through the toothpicks, sounding like rain.
