Water Balloon Cannon // How-To | I Like To Make Stuff

I made this impromptu water balloon cannon for my kids to play with! It's a simple quick project made to be fairly safe. TOOLS LIST: https://kit.co/iliketomakestuff/my-woodworkin… 4" PVC pipe (3' long) 3" PVC cap 1" PVC pipe (2' long) I used a 3' length of 4" and 1" PVC pipe. I also used a 3" cap which fits right inside the large pipe. I traced the smaller pipe on the larger one, marking it a little larger than real life. I marked a cross line several inches from one end. I ran it through the bandsaw which cuts the line on the top and bottom of the pipe, to cut both lines. I used a cut off wheel on a Dremel to trim the piece out. I switched the wheel out for a grinding stone and cleaned off the corners of the cut. This is to cut down on friction. I made sure the smaller pipe fit in the slot and moved freely. Then I made sure there was enough space on each side for a hand, and marked the pipe. I cut the small pipe along that mark then rounded over the ends on the disc sander. Wi
