By following this how-to video to the letter, you’ll be able to make a water balloon-flinging catapult this weekend. All you need are some sections of PVC pipe, a couple of general purpose tools and the wherewithal to put it all together. (Which, frankly, leaves most of us here out.) This video does a fine job of showing the play-by-play, culminating in the launch of a toy cow on top of a far away roof. It’s pretty neat and just the type of project that can help transform a dull weekend into a slightly less dull one.
