What is it one of them there kiddiees linear motor demo kits?
For those in the non uk.d-i-y groups, Brian is blind.
It’s a battery with a magnet on each end which
allows the battery to move in metal spiral.
Idel for launching things that break ornaments.
Not in this case, it runs in the spiral and doesn't
go far if it comes out the end of the spiral. Goes
until the battery is flat if the spiral is in a loop.

Trying to think of how to use that around the house, and not just to keep
the cat amused.
