HOWTO Make a business-card catapault

Instructables user Clide has created a business card that you can assemble into a papercraft catapault! "After seeing the business cards with gears a few months back (normal and planetary), I started thinking about what else could be made to fit in a business card. I wanted something unique and memorable that could represent me and my creativity. What I came up with was a business card that can convert into a rubber band powered desktop catapult."

Cardapult the Business Card Catapult (via Craft)


  1. Haha, at my blog (oops, advertizing? sorry!) I made a response to this. Because really, can’t you just make a catapult out of a business card already? (fold it in half a couple times and send small objects flying across the room?)

    oh well, this idea is awesome, wish I was that smart. I kind of want one now.

  2. Great! I just broke the fluorescent lights over my boss’ desk. Now I’m emptying mine. My lawyer wants to know Clide’s last name.

  3. A cool trick, but not to dash your hopes and dreams.

    You probably shouldn’t put Mechanical Engineer on your business card. Especially if you are still in school. In many states it’s illegal to state that you are an X Engineer if you do not have a PE…

    You can state that you are an Engineer, but not a specific one, as that implies you are licensed in that field.

  4. Sigh. Yet another site I have to register to see/use the material. OTOH, the business card catapult is a DO WANT, although it appears to require an original card with specialized materials and construction; the plans don’t work with just any old card.

  5. Scrolling down the page, I saw this as a catapult made for business cards. Boy was I disappointed to find it was a catapult made from business cards.

  6. I also want a catapult made for launching business cards. That would be speed networking at it’s finest.
