Exploding soap bubbles filled with hydrogen alone
Hydrogen-filled soap bubbles are ignited producing small explosions.
Hydrogen-filled soap bubbles are ignited producing small explosions.
Hydrogen plus some oxygen produces louder explosions.
Hydrogen plus more oxygen produces even louder explosions.
Hydrogen and chlorine gases can be mixed together without reacting, but when the mixture is struck with bright light, it reacts explosively.
This brief animation illustrates the chain reaction that occurs when hydrogen and chlorine gases react.
