Have fun exploring friction with this easy science experiment. All you need is a clear plastic bottle, a bag of rice, a pencil, and a funnel.
- Clear plastic bottle
- Place the funnel in the bottle.
- Fill the bottle all the way with the rice.
- Insert the pencil straight down into the bottle.
- Try to lift the pencil.
- If your pencil slips free, gently tap the bottle on a table to settle the rice around the pencil.
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.
