Jeff Bezos isn't the only person interested in vintage NASA technology. Public and private entities alike are actively taking a second look at the Rocketdyne F-1 engines that helped notch Saturn V rockets as the tallest, heaviest, and most powerful rocket ever operated—even today, forty years after the demise of the Apollo program.

Rocket engines require two important ingredients to fire: fuel, and an oxidiser. And to get the most bang for your buck with those ingredients, you need to find the perfect recipe. As the BBC's Bang Goes the Theory demonstrates with three plastic bottles, maxing out on either ingredient doesn't produce as effective a chemical reaction as ensuring the two are in perfect balance. There's a reason they call it rocket science after all. [YouTube via The Awesomer] Read More >>

For as cool as hurling columns of fire at your enemies is, "flamethrower guy" was one of the most dangerous jobs in the military — one stray bullet and the big canister of napalm strapped to you goes ka-boom and you along with it.

Skyflash is a German DIY invention that involves strapping a wing and a pair of rockets to man and seeing if it all flies. And, as today's latest test video shows, it does. Only at an altitude of a few inches, but it's a good start. Read More >>

Christmas is over. Chances are you still have your tree up, but sooner or later you're going to have to get rid of it. Sure you could unceremoniously toss its naked corpse into the street, but you could also turn it into a crazy rocket.

There's no doubt that the future of this country's space exploration lies in the hands of the private sector. And Elon Musk's SpaceX is clearly at the forefront and the company's reusable rocket, the Grasshopper, is a sight to see.
