The handcuff knot i am about to show you can be used for many things like playing around and joking.
I do not not suggest you use this to tie up a actual criminal and am not responsible for what happens if you do so.
Step 1: Materials
I used about that for this project
Step 2: Make Your Bites
Step 3: Pass Bites Over
Pass the side closest to the left bite over top of it so that the right bite lays on top of the left.
Step 4: Pull Bites Through
Easier seen then explained, see video for better visual
Step 5: Pull Tight
To make the holes bigger for hands to go through, pull on the lower.
Pull on the strings coming from the bottom to tighten.
If nothing is in the loops and you pull on the strings, The knot will release itself.
Step 6: Video
i found this video that does a great way of explaining it
