This one is great to fool your kids. When your kids are asleep the night before April Fools day you use food coloring to turn the milk in the carton blue!

Hang up teabags outside someones room. It's excellent to do this to your roommates for an extended period of time, eventually they will lose it! You'll see :)

When away on April Fools' Day, his roommate thought it was the perfect time for a great prank. He placed 3.500 plastic cups of water all around the house.
