7 nails and a block of wood


How can you balance the six nails on the nail in the wood?
No other objects are allowed, and the nails should balance on the nail, not rest on the wood.

I would like to thank my colleague Theo Sweres for showing this puzzle to me. There is a slight manual dexterity required, but not much. Though this puzzle has been exclusively on logic and math puzzles so far, I’ll add some physical puzzles for variety.
