Henry Ernest Dudeney/Modern Puzzles/141 - The Six Submarines

by : $141$

 * 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.
