Coin+Flick



Key idea: Objects will tend to resist changes to their motion, to a degree influenced by their inertial mass.

You will need: • a 20c coin • a playing card in good condition.

Method: Balance a 20c coin in the middle of a playing card, on top of your index finger. Having achieved this balance, use your other hand to flick the card horizontally off your finger. The coin stays in place!
