We're not quite sure where the name Bucky Balls comes from, but we're pretty sure that we trust whoever came up with it - these tiny magnetic balls make a fantastically addictive game. There's not really any point to it, but the sheer addictive nature of mucking around with a load of magnets will be enough to keep you entertained for a long time.

You can make any shape you like out of them, whether it's a pattern, a necklace, a bizarre Dali-esque sculpture or an attempt at creating miniature version of the cast of The Archers.

Funnily enough, the hardest thing to do is make it into a cube. It's nigh on impossible but that won't stop you from shirking your day-to-day duties in an attempt to complete it.

Fiendishly difficult, a constant distraction and rather good fun all at the same time. Not recommended for train drivers.
