No? Well now you can, thanks to the Oginov tumbler puzzle.
I got my Oginov tumbler puzzle from the bargain bin at my local supermarket, and I don't mind telling you, dear reader, this puzzle has changed my life. Gone is the need to drink 4 double whiskies to get off to sleep. Nor do I need any pills who's brand name begins with Z.
These days, just picking up the plastic ball is enough to make my eyelids start to droop. Within seconds, my head has hit the pillow, and the ball falls from my insensate fingers, causing one of the pieces to topple over, revealing a trendy logo.
Fortunately, this is not exciting enough to wake me up.
