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 )
Step 2: Start constructing
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
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.
hopefully you like it and "PROST!"
