DIY PVC WBL (do-it-yourself PVC water bottle launcher)

Summer is over, and you what that means? It’s time to show you all the fun you could have been having with this homemade water bottle launcher. Now, you’ll have all winter to perfect your design. Oh sure, you’ll probably want to test it out once or twice, but that desire will surely pass once you’ve been sprayed with freezing cold water. Or when you catch your death of pneumonia, depending on how enthusiastic you are about amateur water powered rocket science.
