A reaction container has contains an amount of a water reactive material and a volume of water within the confined space of its interior. The water reactive material, which contains aluminum, is formed as two separate and spaced apart portions. The water is located between the two portions of the water reactive material. A detonation mechanism, which is configured to mix the amount of water reactive material and the volume of water, is provided in communication with each portion of the water reactive material. The volume of water and the aluminum in the water reactive material are stoichiometrically balanced.
