Centrifugal force with a liquid
Get a small goldfish bowl or glass jar. Fasten a wire securely about the neck. To this wire attach a bale. Join the cord from the drill chuck to the exact centre of the bale. Place about 3 cm of water coloured with ink in the bowl. Turn the drill grip to spin the bowl and water. View the effects of centrifugal force on the water.
