Laser Propulsion

D.I.Y. Laser Propulsion

The Breakthrough Starshot project aims to create a Light Sail Spacecraft capable of making the journey to the Alpha Centauri star system via Laser Propulsion.

You can demonstrate this idea with an inexpensive 5 mW Laser and a Crookes Radiometer.

In this analogy, the processes are different - photonic propulsion (Light Sail) verses thermal transpiration (Radiometer) - however, both models use the same energy delivery mechanism, a laser, with similar results.
