Try to escape my homemade trap

Budget is $80. Paypal or cash app. USA only due to shipping logistics

For this request, I will mail you a homemade object. Once you receive it, you will trap yourself in it, in the way I describe. There is a trick to escaping it, and I want to see a video of your attempt at figuring it out.

If you fail the challenge, I will give you the solution. But I might tease you and make you beg first!
