SUMMARY

The discussion centers around an unidentified piece of equipment found in a store room, suspected to be a scattering demonstration apparatus. The device, manufactured by Welch, features a tube that appears to squirt a substance onto a spinning wheel, allowing for observation of the scattering pattern. The user recalls a similar apparatus used in educational settings for angle measurements and impact analysis, suggesting its purpose is likely educational or experimental in nature.

PREREQUISITES
  • Understanding of scattering experiments in physics
  • Familiarity with laboratory equipment and their functions
  • Knowledge of angle measurement techniques in experimental setups
  • Basic principles of mechanics related to motion and impact
NEXT STEPS
  • Research the specific functions and applications of scattering demonstration apparatuses
  • Explore the design and mechanics of similar educational lab equipment
  • Learn about angle measurement techniques used in physics experiments
  • Investigate the history and products of Welch as a manufacturer of scientific equipment
USEFUL FOR

Students, educators, and laboratory technicians interested in experimental physics, particularly those involved in teaching or demonstrating scattering phenomena and angle measurement techniques.

I just found this in my store room. Anybody have any ideas what it is?

No. But my guess is some kind of scattering demo? You squirt something from the tube to the (spinning?) wheel and see where it goes as you move the nozzle side to side.

What do we win if we guess right. Kewpie dolls, or cash?

Other than the manufacturer sticker 'Welch", I don't see any information. What's on the bottom side of the base plate?
 
It's just flat particle board. The only thing that seems to move is the little tube along a spring loaded screw. The center seems to be just an immobile piece of glass.
 
Reminds me of a scattering apparatus in a student lab which I tutored. There was an adjustable mechanism which shot small metal balls onto the central target. On the rim there was a special paper which acquired black dots upon impact which made angle measurements possible. The angle measurements were then used to infer information about the target.
