Picture of Catapult Bottle Opener


I want to present you my prototype of a bottle opener, which reminds me of some kind of catapult.

First of all, here's a video of how it works

In the video you cant see how far the bottle cap flies, but i can tell you: It flies through the whole room and you might have to search it. And beware: Dont let somebody stand in front of the bottle opener, he might get hurt ;-)

PS:I hope you can understand me, Im from Germany ;-)

Great idea! Here's my foldable version with a little hinge to make it easier to carry or store :)

This looks like it should be the end move in a fantastic machine involving candles, swinging arms, burning strings, bowling balls etc and ultimately resulting in the opening of your beer!

Fab' idea.

This is awesome! And to think I've been opening bottles with a regular old bottle opener this whole time!

Google "Traction Trebuchet". That's what you've made to open bottles. Very cool.

Good build!.

To address the problem of the 0,33L (or as we in the USA would say, 12 ounce) bottle, consider a fold-down block of wood fastened next to the uprights. It would increase the price of the device by the cost of a hinge, unless you have a box of salvaged hinges, as I do.
