Density Spheres

  • Steel spheres above have equal mass. Larger sphere is less dense than water; smaller sphere is not.
  • located in L02, section D1 (or D2).

  • Marshmallow enlarges to about twice its size when placed in a vacuum.
  • Marshmallow then deflates to about half its original size when removed from vacuum.
  • Dense marshmallows feel heavier (illusion), and taste better (not illusion!).
  • Vacuum chamber, pump, and marshmallows located in L02, section D1.

Bounce/No-Bounce Balls

 

Bounce/No-Bounce Balls

  • Balls look and feel identical, but due to differences in
    elasticity one ball bounces and one doesn’t.
  • Located in L02
