I3-15: MAGDEBURG HEMISPHERES - PORTABLE
Additional Info
- ID Code: I3-15
- Purpose: Demonstrate forces arising from atmospheric air pressure.
- Description: About 40 pumps will adequately evacuate the hemispheres, and the vacuum will last about one minute. The hemispheres have a diameter of about 5 inches, thus requiring a force of over 250 pounds to separate them when fully evacuated. A safety restraint prevents the two hemispheres from separating entirely.
- Availability: Available
- References: REFERENCES: (PIRA 2B30.30)
- Loc codes: I3
