How to Fill a Water Balloon With Jello. A twist on the traditionally filled water balloon involves jell-O. Instead of filling those balloons with water, many adults and kids use jell-O for their water balloon events. Imagine a person's surprise when that balloon goes splat and cherry red or lime green jell-O gushes out.
Things You'll Need
- Jell-O Packets
Select a box of the Jell-O flavor of your choice. Choose appropriate colors for parties such as lime green Jell-O for Halloween. Cherry Red is great for summer parties on the Fourth of July.
Prepare the Jell-O according to the box directions. Do not refrigerate. Once the Jell-O has been mixed and all water added, move to the next step.
Fill a small balloon with air. Thin wall, small balloons work well but experiment with different types of balloons.
Place the balloon's opening around a small funnel. Use your fingers to hold the balloon to the funnel.
Pour the Jell-O into mixture into the balloon using the funnel. Do this until the balloon has a good shape. Do not overfill the balloon.
Tie the end of the balloon once it is filled. Use either string, balloon clamps, or twist the balloon's opening into a knot to tie it.
Place the Jell-O balloon in the refrigerator to set for a few hours.
Repeat Steps 3 to 6 for each balloon.
To create many balloons, purchase many large boxes of Jell-O.
