A hole 10 feet deep, and containing a charge of 10 lbs.

However, some holes contained clues saying "Try again"

Apparently this is not possible; one hole must contain a single pebble.

Those holes, the French group said, contain a wealth of opportunity for research.

If the hole contained three items it became known as a pur-3, four items a pur-4, and so on.

Yanoviak found that the holes contained only 400 ml of water on average however.

The first hole of the dial contained the number: one, but no letters.

This hole contains a total of 16 bunkers, making for accurate shots from tee to green.

The small hole in the front of the crown contained a camera assembly.

Each hole contains a single plastic mole and the machinery necessary to move it up and down.
