This is a prank involving water. Only do this prank outside to a friend who will think it is funny, not one who is easily annoyed, because this will annoy an easily annoyed friend.
Step 1: You Will Need:
You will need:
1. A Tennis Ball
2. A SHARP Knife
Step 2: Cut the Tennis Ball
First of all, cut the tennis ball carefully with the knife into two halves.
Step 3: Bring the Tennis Ball Over to a Sink
Next, bring the two halves of the tennis ball over to a sink.
Step 4: Fill One Half With Water
Now fill one half of the tennis ball with water.
Step 5: Place Other Half on Half Full of Water
Next, place the other half on the half that is full of water.
Step 6: Squeeze Both Halves Together Tightly
Now squeeze both halves together tightly.
Step 7: Cock Your Arm Back And... Fire!
Finally, cock your arm back, aim at your friend, tell him/her to catch, and fling your arm forward while releasing the ball in a nice lob that is easy to catch. Your friend will soon turn into a wet, angry monster, so have a camera ready to snap some pictures and to post the on Facebook. ;)
