Custard Rocket   (+2, -1)  [vote for, against]
Ok, I'll throw my hat into the custard filled ring.

Many things are flammable when put into powder form and custard is more flammable than most. So let's say one were to blow custard powder across a flame and mix in a bit more pure oxygen. You'd have a rocket with efficient kick to break out of the atmosphere. Custard powder is also lighter than many fuels out there.

Custard / ammonium nitrate? Where's [8th], there's some munitions here that need handling!

Well, yes and also no. But at least the exhaust would smell nice.

// Where's [8th], //

Crouching down behind the sandbags. Believe it or not, custard powder, cornflour, starch, and the like are viciously explosive in confined spaces. Grain elevator explosions are tragically all too common - that's cereal dust.

You might just be able to get a solid fuel propellant out of the mix but if you ended up with a stoic mixture it could all get rather loud and expensive.....

This is an example of the kind of idea i wasn't talking about, as it doesn't depend on viscosity.

//a stoic mixture// What, does it say to itself "well, I'm about the blow up, but I'll just put up with it"?
