SUBMIT: Your Favorite Completed DIY Project by August 8th. WIN: How-To Book, Mini Weapons of Mass Destruction [Closed]

Giveaway Tuesdays has officially ended! But don't sweat it, WonderHowTo has another World that's taken its place. Every Tuesday, Phone Snap! invites you to show off your cell phone photography skills.

Submit your best shot to our weekly competition for a chance to win an awesome prize. Phoneographers only—both Android and iPhone welcome! Check it out now.

UPDATE: As duly noted by Kerec Tunca (scroll down), this week's past Challenge has been a bit of a dud. Thank you to the four users who did submit—we enjoyed seeing your projects. This week's winner(s) are: Matthew Herman for his in-the-spirit-of-Mass-Destruction potato cannon, and Kerec Tunca for his charmingly scrappy camera tripod (thanks for including the tutorial!).

This Giveaway Tuesday is all about the "I Made It". It's simple—as members of WonderHowTo, you've likely got a DIY project or two under your belt that you're proud of. We want to see what you've done! Post your project to the Giveaway Tuesdays corkboard for a chance to win the nefarious DIYer's holy grail: Mini Weapons of Mass Destruction by John Austin.


Toy designer John Austin's MacGyver-inspired book turns common office supplies—binder clips, clothespins, rubber bands, pens, toothpicks, paper clips, matches—into mini slingshots, catapults, mines and bazookas. Specific projects include step-by-step instructions for Shoelace Darts, Clothespin Catapult, Penny Bombs, Airsoft Pen Poppers, Ping Pong Zookas and approximately 40 more. Selected by Popular Mechanics as one of the best DIY books of 2009, we've also previously featured Mini Weapons of Mass Destruction on WonderHowTo.
