This Ancient Technology Makes Things Spin Really Fast!

Summary by Krater

The video demonstrates how Hero's Engine works, testing its rotational speed using steam, and then experimenting with liquid nitrogen inside a ping-pong ball to make it spin at high speeds.

From the video

Answers: How does Hero's Engine work and how fast can you make a ping pong ball spin with liquid nitrogen?

• Hero's Engine physics
• aeolipile principles
• liquid nitrogen ping pong ball experiment
• rocket propulsion science
• tachometer speed measurement

What it concludes

• Hero's Engine uses the same principles that power modern rockets, steam turbines, and jet engines.
• Liquid nitrogen expands by 700 times its original volume when it turns into a gas.
• Hero's Engine is not an energy source, but a method to transfer stored energy.
• Hero's Engine did not revolutionize the world when invented because the technology to harness steam effectively did not exist yet.
