Aeolipile: The aeolipile, often called "Hero's engine," is known as the world's first steam engine, invented by Hero of Alexandria in the 1st century AD. It demonstrates the fundamental principle of jet propulsion and Newton’s third law of motion. I saw a video of it on YouTube and decided i want one. But nothing too complicated. I made this spinning top that uses that principle. Blow on the top opening and air will be redirected with the help of the walls, spiral and sharp slope. It will then exit the spinning top by the 8 openings at high speed. So high that the spinning top struggles to maintain balance (It doesn't fall over, just makes a rattling noise). The print profile includes the top and a stand to put it on your desk when you're not playing with it. The stand doesn't grip the top too tight to allow it to spin.
