Are you struggling to get the ball off the magnetic cannon? Fingers to big? Nails too long? Then this is a useful tool to remove the ball. Wedge it between the ball and the cannon and pry it off the magnet. I have replaced the magnets in my cannons with a stronger ones. Trust me, you will appreciate this tool :-)

Here's a video with most of the elements in my library. And... a preview of the lapse timer I am about to release. The lapse timer has custom electronics that I will be making in small batches. If you are interested in the lapse timer drop me a message. If there's enough interest, I could consider ordering larger batches of circuit boards and components.
A neodymium disc magnet is required. 6mm round and 4mm in height. Use a dab of CA glue to hold it in place.
Note the orientation of the handle when glueing in place.
Enjoy!
