Paddle Wheel Cathode Ray Tube
Product Code : JA-APE-9394
The Paddle Wheel Cathode Ray Tube (SKU JA-APE-9394) is the Crookes tube that shows electrons have mass and momentum. In this paddle wheel Crookes tube, the stream of electrons from the cathode strikes the vanes of a small, freely moving paddle wheel and sets it moving, so students can see a mechanical effect produced by cathode rays. It belongs to the set of four Crookes tubes used to demonstrate the properties of electrons.
Specifications
The tube is a highly evacuated, fragile glass Crookes tube containing a paddle wheel; once mounted in its holder it is run from a variable 2-12 V DC supply and a high-voltage DC source through two sets of connecting leads.

Demonstrations with the paddle wheel tube
The moving paddle wheel gives students a visible, mechanical sign that cathode rays carry momentum, which supports the idea that they are streams of particles with mass rather than waves of light.
- Showing that cathode rays can set a paddle wheel moving
- Demonstrating that electrons have mass and momentum
- Linking cathode ray observations to the particle nature of electrons
- Class demonstrations alongside the Maltese Cross and deflection tubes
