Remove the label from a clean, clear plastic soda bottle. Then gather a bunch of trinkets, such as beads, buttons, charms or plastic insects, and put them in the bottle. Add uncooked rice to fill the bottle two thirds of the way, then tightly screw on the cap.

Shake well to conceal the objects. Now your child can twist and turn her toy to see how many treasures he or she can spot inside.

Note: Objects such as coins and pebbles tend to gravitate into the middle, while lightweight plastic beads, buttons and trinkets are easier to spot.
