It was a crowded playing field on Monday , with commenters weighing in on everything from zombi - cake to the first families of science fabrication to the secret motive of flesh - eating plants , but only one comment can be input of the day and today that comment comes fromRod Brock .
He share this bit of trivia , responding to“The Union Jack on the Moon,”about what rocket fuel is made of and it ’s surprisingly pencil eraser - comparable consistency :

If memory serves me , the solid fuel boosters on the Shuttle were be of a mixture of pulverised atomic number 13 , ammonium perchlorate ( oxidant ) , iron oxide , and an epoxy resin binder . The final result was a product about the consistency of a pencil eraser ; this semi - soft quality is important because the way solids work , with a hollow marrow , it is potentially disastrous if any cracks should develop in the grain , because the fuel will burn along the distance of the crack , quite likey cauterise through the extinct cuticle of the roquette and causing a catastrophic failure .
You learn something Modern everyday , and today that thing is what arugula fuel feel like .
