Not bizarre, but a useful tip from Chethams.
When practicing with just one hand let the other rest gently on the keyboard rather than on your lap or on the piano stool - where it distorts you position and your sensations.
By keeping the reting hand close to a normal playing position you achieve the correct balance of the body and the correct position of the arm and hand that are practicing.
Plus, this has the advantage that when you're sight reading something and one hand isn't doing anything for a while, its still in more or less the right place when it comes back in, and prevents any sort of hiatus when it starts playing again.
Similar to the bits of paper, pennies, rubbers etc on the back of the hand, I was told to _imagine_ a glass of water.
