Here is how you can make your own water balloon launcher. We use heavy duty surgical tubing unlike many of the blasters you can buy online that don’t shoot very far. Materials cost is approximately $18. This instruction covers only the launcher. See the Water Balloon Launch Pad Instructions for the frame.

(1) small roll of duct tape
(2) 8 inch lengths of 1/2″ vinyl tubing
(2) 6 foot lengths of latex rubber surgical tubing

Vinyl tubing can be purchased at a hardware store. Latex rubber tubing can be purchased online. A good source is McMaster part number 5234K75 . It must be 3/32″ thick wall (not 1/16″ thick). Surgical tubing sold at hardware stores is typically only 1/16″ thick and not strong enough to launch a balloon 300 yards. If you are in a pinch and don’t have time to order the thicker tubing, then you can double-order. top the 1/16 inch of tubing, but that is quite expensive.

Step 2: Bag Design

Take 2 pieces of ribbon 7 inches long and fold over a 1/2″ edge to create a hem. Place the 2 hemmed pieces facing each other about 3 inches apart on 5 pieces of tape.

Step 3: Add Pipe Channels

It’s a 3-man launcher but we’ve added a water balloon launch pad that only requires one person to load and launch. Have fun!
