MECHANICAL ROTATION PUZZLE

I give you my rotating hidden compartment puzzle! inside are six springs, a bearing and a steel ball bearing. The springs and bearings at the top let the handle spin and be pulled up to confuse what is happening inside.
The neodymium magnet holds the steel ball bearing at the bottom until you pull up the handle and give the puzzle a shake to release the BB. You can then twist the handle until the BB drops into the slot and the key engages into the main body and locking the handle and it being able to unscrew. I added a sliding hidden compartment that you can only open by using the rotating handle to gain access. you can put a money or a note inside as a challenge for anyone that can figure it out.
