From the Forum of Rocket Models:
I made a large solid-fuel-free rocket engine, and in order to test this concept, I attached a piece of the door to it, set it on fire, and threw it out of the window. I admit, you are an idiot. It flew above the house, where it was turned over by the wind, and it moved towards the road. In the hood of the peacefully travelling nine, a smoking and sparkling doorstep was spotted, pushing up to a terrible speed. What will I be?
