They don't. Try filing the balloons with mashed potatoes instead.
Most sporting good stores sell them, now called wrist-rockets sling shots.
To use a water balloon launcher, follow these steps: Fill a water balloon with water. Place the water balloon in the pouch of the launcher. Pull back on the launcher and release to launch the water balloon towards the target.
If plaster is put on a water balloon, the plaster will absorb the water content from the balloon, causing it to harden. This can result in the balloon deflating as its water content is absorbed by the plaster, leaving behind a hardened plaster shell in the shape of the balloon.

A water balloon is filled with water, and other balloons are filled with air or helium.
you have made a water balloon!
A balloon filled with air will float on water because it is less dense than water. The buoyant force acting on the balloon allows it to float.
To inflate a water balloon, stretch the balloon opening over a faucet and turn on the water slowly until the balloon reaches the desired size. Alternatively, you can use a water balloon pump to inflate the balloon. Just make sure not to overinflate it to avoid bursting.
The amount of water that a water balloon can hold before it pops depends on the size and quality of the balloon. Overfilling a water balloon can make it more likely to burst. It is best to follow the manufacturer's guidelines for filling the balloon.
The amount of water in a water balloon can vary depending on its size. On average, a standard water balloon can hold around 8-10 ounces of water.
Water is attracted to a charged balloon because the balloon's electric charge creates an electric field that polarizes the water molecules, causing them to be attracted to the balloon.
To design a device that converts the expansion and contraction of a balloon into usable work, you can create a system with a balloon attached to a lever mechanism. As hot water circulates through the balloon, it expands, lifting a weight (like a rock) attached to the lever. When cold water is circulated, the balloon contracts, lowering the weight. This cyclical process can be harnessed to perform repetitive work, such as lifting and lowering the rock with each temperature change.
