Specifications

Explanation

In an underwater explosion test, the energy released during an explosion can be accurately measured.

The water in this pool is kept clear, in order to allow explosions and resulting destruction of submerged structures to be observed safely.

On the right, a gas ball resulting from detonation of 10g of explosive is shown. Because high pressure gas is released very quickly, a clean sphere of gas is developed.
