Algodoo

"Quick Release Nut". Some people have addressed me that way!

It's a very clever design, and you did a great job of depicting it in your scene.

Added thought: Would it be important to show the two magnets in the scene? Apparently, this device won't work properly without them.

Q: Would it be important to show the two magnets in the scene?
A: I purposely didn't show them so people can wonder how it's done in real life and in Algodoo. Apparently, judging from the view to download ratio, 90% of the users either figured it out or just don't care enough to dig deeper. I initially tried to make the nuts magnetic using Algodoo attraction but failed. I will add a note to the scene just to make it easier on the users so they don't stay awake late at night trying to figure out how it's done.

Reply: Oh, totally awesome. Now I'll finally get some sleep!
