Release Mechanism Explained! Check It Out

THIS IS NOT MY DESIGN, I TAKE NO CREDIT WHAT SO EVER FOR THIS But Please Enjoy Materials needed for the powr:

• Big plastic soda bottle
• Small soda bottle
• Paperclip How to put the powr together:

1. Cut the big bottle in two parts, making sure that the bottom part is somewhat taller than the upper part 5.jpg 5.jpg (7.92 KiB) Viewed 4931 times
2. Pinch a tiny hole in the cap of the big bottle, using for instance a needle 4.jpg 4.jpg (6.56 KiB) Viewed 4931 times
3. Now take the small bottle. Cut it in half so that it will fit into the bottom part of the big bottle. This will be used as a float that will eventually trigger the release. 3.jpg 3.jpg (6.77 KiB) Viewed 4931 times
4. Take the paperclip and straighten it out. Attach it to the cap of the small bottle in such a manner that the paperclip can still be tilted up and down. (Use a piece of wire, rope, …) 2.jpg 2.jpg (7.37 KiB) Viewed 4931 times
5. Now make a hole in the wall of the big bottle for the paperclip to fit through. This hole should not be tight. 1.jpg 1.jpg (6 KiB) Viewed 4931 times
6. There you go! Fill the upper part of the big bottle with plain tap water, slide your keyring over the paperclip, hang the powr to your ceiling, tie yourself up and feel powrless The above one released the keys after 3 hours, but the time can easily be adjusted by varying the size of the hole in the cap. You could make a series of different caps and label them. Put them in the closet, and you’ll have them available at any time. Be sure to play safe and share your experiences!
