Family and Children's Activities

Grab an old towel, several feet of surgical tubing, two small pieces of wood (about 6" long), duct tape, and scissors. Cut the towel into a 14"x14" square, then cut a 3"x3" square out of each of the four corners to create four tabes. (The cloth should now resemble a fat plus sign.) Fold one piece of wood into the top and bottom tabs, and use the duct tape to seal the material in place. Fold the tubing in half, then lay it over the remaining tabs so that one line of tubing hits each piece. the cloth should evenly divide the remaining tubing, so you will have equal amounts of excess lying on either side. Fold the tabs over the tubing and seal them shut. Now you're ready to launch. Tie the free end of the tubing to a tree, then hold the other side in your hande to provide tension. Have you child place a water balloon in the pocket, pull back, and wait for the splat. For more detailed instructions, see instructables.com.
