Prank someone by making a pre-sliced banana that will fall to pieces when someone unpeels it. They'll have no idea you've already tampered with the fruit for this prank. You'll need a needle and some time to covertly slice the banana while it's still unpeeled. This is a great practical joke or prank to pull on a gullible friend. Use this as inspiration for one of your April Fools Day pranks!
