Holy Hand Grenade of Antioch

This is Monty Python`s Holy Hand Grenade of Antioch in its fancy version. Useful references are:

The body can be replaced by a sphere with a diameter of 14 cm if you feel this is better.

I mounted the pin with a screw on its base and a magnet inside the grenade body. It worked very well, but other options are valid. This detail is an incentive to your creativity.

Use it to destroy the Rabbit of Caerbannog, but don't forget to count to three.
