Build a Business Card Catapult to Prepare for Office Warfare

If you’re in desperate need of some siege weapons to defend your cubicle kingdom, this novel little hack turns card stock into catapults.

Bryce Bell is somewhat of a papercraft master at arms, turning card stock into all manner of siege weapons. In the above video he demonstrates his “Cardapult” a card stock based catapult. He’s also built a “Trebucard”, a trebuchet like paper clip launcher:

Jason Fitzpatrick is a warranty-voiding DIYer who spends his days cracking opening cases and wrestling with code so you don't have to. If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). You can follow him on if you'd like.

    Ingenious. A few of those could tip the balance of power in those dreaded cubicle wars. I imagine the next step in this armament race will be a card version of the Cruise missile. And by the way, “r”, did you ever learn the meaning of the word “fun” while in kindergarten?

    Don’t know really. In kindergarten I was likely too young to consider the “meaning” of the word fun.
    However, as I grew up I learned how to have great fun within relation to things like age, knowledge, experience & maturity. Thanks for the concern…you?

    This could swing the war in our favour at work. Thank you.
