How geeky? :)

Never let it be said that us Mansfield lot don't know how to have a good time. ?

Got some geeky science toys to play with...

A circular Halbach Array with magnetic force viewer. Google it!

Magnetic sand timer.

Gyroscopic powerball.
The powerball weighs next to nothing, but shake it, and the internal gyro automatically starts spinning up to a maximum of 22000rpm, that's 366x per second! By 10000 revs it is gyroscopically generating a force of over 11kg! It has a built in digital rev counter. Good for weight training arm and wrist muscles or even rehabilitating pulled muscles. I've got a badminton injury to my extensor carpi radialis longus. Say that after a couple of pints. ?
