Homemade Super Soaker Water Blaster

Step 5 Making the barrel

Get a short length of PVC pipe about 25mm in diameter and about a foot long.

Cut a circle of wood that will fit inside the end of the pipe and drill a hole large enough for the hose to just pass through. Hot glue this in the end of the pipe.

Take the end off the disposable pen, or if yours doesn’t screw off, cut it off.

put a tiny bit of hot glue on the inside edge and push some 5mm clear hose (about 2ft long) in to it (in the pictures its the black tube I am using but I changed that out because it collapsed when it got bent and restricted the water flow)

push the hose through the hole in the wooden disc in the end of the pipe until the end of the pen is flush against it, then hot glue it in place taking care to make sure its straight.
