Did you know you can turn a banana into a hammer when the temperature outside dips below freezing?

Materials

* Nail

* Board

Instructions

STEP 1: When the temperature gets below freezing place a banana outside before bed.

STEP 2: When you wake up in the morning, grab a nail, board and the frozen banana.

STEP 3: Using the rock-hard banana, hammer the nail into the board.
