Setup with
Science-
Workshop
and a
Pressure
Sensor
To obtain qualitative information about the force required to offset atmospheric
pressure, set up the Magdeburg Plates without
ScienceWorkshop
.
1.
Pull vacuum (usually requires 3 or 4 pulls on the syringe plunger).
Note:
The vacuum deteriorates slowly, usually over a 10 – 60 minute
period.
2.
Disconnect part F
from part E. (Check
valve in part E
maintains the
vacuum) (Figure 5).
3.
Grasp both handles
and pull (individual
or “tug of war”).
