Rocket Hobby model

Once upon a time, there were no Grabcads, PCs, or smartphones, but kids fell deeply in love with creating all sorts of models. And yes, one particular model that captured their hearts was the rocket: its body and fins crafted from paper, while its nose cone was carefully made from wood. The engine, a potent mixture of 68% potassium nitrate, 17% carbon, and 15% sugar, lay at the heart of this miniature marvel. But beware, even the most skilled kids needed to handle it with care - one misstep could send it soaring out of control, causing harm to anyone nearby!
