Multiple Faces of Hydrogen-Peroxide H2O2

 Hydrogen peroxide (H₂O₂) is a common household disinfectant and bleaching agent, but it also has some unusual and lesser-known properties:

1. Rocket Propellant: H₂O₂ can be used as a rocket propellant. In high concentrations (above 70%), hydrogen peroxide can act as a monopropellant, decomposing into water and oxygen, releasing a large amount of heat. This makes it a powerful oxidizer and fuel for spacecraft.

2. "Fangs of Death" in Nature: Some species of bombardier beetles use H₂O₂ as part of their defense mechanism. When threatened, the beetle mixes hydrogen peroxide with hydroquinone and enzymes in a special chamber. The resulting reaction creates an explosive, boiling-hot jet of chemical spray that can reach up to 100°C, deterring predators.

3. Bleeding Underwater: In the deep ocean, certain bacteria can metabolize hydrogen peroxide naturally. They convert it into oxygen, which they then use for respiration. This bizarre ability to "breathe" hydrogen peroxide helps them survive in environments with low oxygen levels, such as hydrothermal vents.

4. It Glows: Hydrogen peroxide is a key component in chemiluminescence, the process that causes things like glow sticks to light up. When mixed with certain chemicals like luminol or peroxides, the release of oxygen from H₂O₂ creates an eerie glow, often used in forensics to detect blood stains.

5. Sensitive to Light: Hydrogen peroxide is highly unstable when exposed to light, which is why it's typically stored in dark, opaque containers. In light, it breaks down into water and oxygen, rendering it ineffective over time. This photoreactivity is why even diluted solutions can "fizz" and bubble when exposed to light.

6. Elephant Toothpaste Experiment: When hydrogen peroxide is mixed with dish soap and potassium iodide (or yeast), it creates a rapid, foamy eruption, often used in science demonstrations known as the "elephant toothpaste" experiment. The reaction rapidly decomposes H₂O₂, releasing oxygen and creating huge amounts of foam.
