This homemade toy may look like nothing more than a bottle of rice, but roll it once or twice, and a host of hidden objects will appear before your eyes.
Objects such as coins and pebbles tend to gravitate into the middle, while lightweight plastic beads, buttons, and trinkets are easier to spot.

Remove the label from the soda bottle.
Gather trinkets and put them in the bottle. Then add uncooked rice to fill the bottle two thirds of the way and tightly screw on the cap. Shake well to conceal the objects.
Now twist and turn the toy to see how many treasures you can spot inside.
