Air
Cannon 
 A
blast of air will startle and wow those who dare to try the air cannon. A
solid thump on this amazing contraption will compress the air within and
send it across the room to perhaps an unsuspecting friend. Try it on a
friend with long hair!
Magic
Mirrors
 A
series of three curved mirrors demonstrate that reflected images play
interesting tricks. As participants change position in front of the mirrors,
distortions occur in the reflected light causing them to appear shorter,
taller, fatter or thinner.
Zoetrope
 This
forerunner of the motion picture consists of a drawing table and a rotating
drum. Make your own drawing in 12 segments, put it in the drum and watch
your picture come to life. Cost is .25 per sheet.
Frozen
Shadows
 One
of the most popular exhibits on the Center's floor, it demonstrates the
physics of light and motion. Creativity and fun is the name of the game with
this exhibit, as body motions are "frozen" on a reflectorized
wall. Fun for young and old.
Harmonograph
 The
only device that requires assistance from Center staff, it is highly
effective for showing how motion and friction relate to one another while
producing fascinating drawings and patterns. Participants can take their
drawing home. Some children have become very proficient and creative on the
harmonograph.
Hot
Air Balloon
 The balloon rises to the ceiling when filled with hot
air by pressing a button, returning to its original position
after cooling. This exhibit helps to explain molecular motion
as related to heat, and the effect of temperature on the
density of air.
Puzzles
 A
variety of puzzles are available that require some serious thought and
dexterity. Take 'em apart and put 'em back together, a challenge to be sure
for those inclined to this activity.
Bubble Race
 Three
tubes filled with liquids of varying viscosity are available for
experiments. Both large and small air bubbles are introduced at the bottom
of each tube. As the bubbles rise, many different patterns and speeds can be
observed.
