How it Works:
The friction between the rice grains and pencil become so strong that you can lift the bottle without the pencil slipping free.
Make This A Science Project:
Try different items in the bottle to see if the friction is strong enough to hold onto the pencil. Try different sized bottles. Try items other than pencils in the bottle to see if they work.
