Requires a bit of tinkering for success
The Jumping Discs work, but they are quite finicky. When you activate them, they immediately snap back. It wasn’t until I bent the discs a little more that they started working well. With some slight adjustments, you can prepare the discs so that they only trigger after 30 seconds or more. This was a special aspect for me since I use them as a prop for a magic trick.
Please bend them very carefully. If you go too far, they might stop working altogether.
