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 ;-)

Step 1: What You Need

  • scrap wood (~0€)
  • a screw with a "V-shaped head" (~0€)
  • 8 small nails (~0€)
  • some metal stick or a longer nail (~0€)
  • a drill
  • a screwdriver
  • a hammer
  • ~1h of time
  • (optional: friends to impress ;-P )
<p>kipkay liked my idea and made an awesome video tutorial. Lets have a look :)</p><p>https://www.youtube.com/watch?v=BkvjkIlqHbI</p>
<p>Great idea! Here's my foldable version with a little hinge to make it easier to carry or store :)</p>
Pretty fun build!! Planning on cleaning mine up a bit.
Built two but without using measurements from the post. Genius!
<p>Wow, very clever. If I build this, I will wear goggles 1st! :) </p>
<p>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!</p><p>Fab' idea.</p>
<p>This is awesome! And to think I've been opening bottles with a regular old bottle opener this whole time!</p>
<p>Google &quot;Traction Trebuchet&quot;. That's what you've made to open bottles. Very cool.</p>
<p>Good build!.</p><p>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.</p>
