【To all users】

  • With the glass tube we can observe and compare the free fall of objects under atmospheric pressure and under vacuum.
  • There are pieces of objects with different mass such as feathers, papers and metals inside of the glass tube.
  • When the glass tube under the atmospheric pressure is inverted, the objects fall to the bottom from top of glass tube in order of their mass.
  • When the glass tube under the vacuum state is inverted, the objects fall to the bottom from top of glass tube at the same time.

【To teachers】

  • The demonstration of free fall motion of object is easily shown to students in both states (atmospheric and vacuum) at a science lab with a vacuum pump.

【To students】

  • Students can observe the comparison of objects motion under two conditions, one is under normal atmospheric pressure and the other one is under vacuum.
  • Maretial: Glass
  • Diameter of tube: φ50 × 1000mm
  • Object samples: 3 kinds (feather, paper, metal)
