Step 1: Supplies
You will need the following supplies:
1. Water Balloon full of water.
2. Needle Nose or Long Nose pliers
Step 2: Wrap
Wrap the water balloon around the pliers.
Step 3: Twist
Twist the water balloon once around the wrap you just did.
Step 4: Grab
Open up the pliers a little bit and grab the end of the water balloon's air nozzle.
Step 5: Pull
Use the pliers to pull the water balloon's nozzle through the wrap while pulling on the water balloon with your other hand. Try pulling quickly to make a secure knot.

Your water balloon is ready to throw. If you have one person fill the balloons and one person tie, you should be able to tie a hundred water balloons in just a few minutes.
