| Rocket propellants come in two parts, fuel and oxidizer, which work together to keep an engine burning. |
| A third type, called a hybrid, combines a solid fuel with a liquid oxidizer. |
| Let that dry for an elegant metal finish, or apply the patina topcoat or rapid rust oxidizer for a unique variety of aged finishes. |
| Fire: Not combustible, but substance is a strong oxidizer and heat of reaction with reducing agents or combustibles may cause ignition. |
| It is a very powerful acidic oxidizer which can ignite or explode on contact with many materials. |
| This engine, like other hybrids, uses nitrous oxide as liquid oxidizer, but uses paraffin rather than rubber as the engine's solid fuel. |
