Preschool Projects: Rain bottle.  Pour rice in bottom and toothpicks on top and when flipped over sounds like rain.

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 inches at the top. Seal the lid. As you gently turn the bottle, the rice falls through the toothpicks, sounding like rain.
