This is a two part special cache that will bring a smile to most faces it's simple when you know how it works!
The finder needs to remove the wooden stopper from the tube and use the magnet in the end to lift the ball bearing to the top and retrieve it for further use!
Remove the stopper from the top of the box and drop the BB in the hole, now lift the rod on the top of the box which will allow the BB to drop into the lower section and actuate the base section when the rod is pushed back down!
The BB is held by a magnet on the drop base so it's not lost in the undergrowth.
Take a look at the Youtube clips to see more.
A waterproof container, logbook, pencile & screws are supplied as are spare BB's incase these go AWOL
