The Six Submarines

If five submarines, sunk on the same day, all went down at the same spot where another had previously been sunk,

how might they all lie at rest so that every one of the six U-boats should touch every other one?

To simplify we will say, place six ordinary wooden matches so that every match shall touch every other match.

No bending or breaking allowed.
