Hello,
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 ;-)
Teacher Notes
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
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 )
Step 2: Start Constructing
Well,
this wood construction is not really hard to create, even for beginners.
You just need the attached sketch and follow these steps:
- Cut your scrap wood
- Optional, but recommended: sand and paint or oil or varnish the wood
- Nail the wood together
- Drill the holes for the metal stick
- Screw the screw into the lever
- Put all parts together
Done :-P
I think this undetailed description is sufficient to create the bottle opener, because its really simple.
Step 3: Prototype Thoughts
I initially made this bottle opener for 0,33L bottles but after some tests, it sometimes (not often) happened, that the 0,33L bottle foamed over.
So, I tested the bottle opener with 0,5L bottles and they never foamed over.
--> If you want to create this bottle opener for 0,33L bottle, you have to construct the lever a little bit lower, with a similar angle like with the 0,5L bottles.
OK,
hopefully you like it and "PROST!"

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.
