Rope Puzzle 2

Get the rope out of the pipes. Solve the puzzle by looping the rope around the blue pipe, and then transfer it to the red pipe. Move the rope to the yellow pipe. Get the rope out of the blue pipe. The rope puzzle is an example of topology, a branch of mathematics.

Animal Sounds

A sensor has been placed in the eye of each animal. When you cover an animal's eye, it blocks the light reaching the sensor. The sensor responds to the blocking of light by closing the electric circuit and this turns on the switch for the sound. The sounds you hear are recordings of sounds that real animals make.

Bicycle Wheel Gyro

When you tilt the wheel that is spinning inward to the right, you (on the chair) rotate to the left. When you tilt this spinning wheel to the left, you rotate to the right. When you tilt the wheel that is spinning outward to the right, you rotate to the right. When you tilt this spinning wheel to the left, you rotate to the left.  The exhibit demonstrates Conservation of Energy.

Symmetroscope

See the drawings of parts of objects on the disk at the back end. Look through the opening of the three-sided tube.  Slowly rotate the disk until a part of an object fits a corner formed by two sides of the tube. The drawings on the disk are parts of circular objects. As a part fits a corner formed by two sides of the tube, that part is reflected by the three mirrors. The reflections bounce back and forth. This is why you see many reflections of whole circular objects–a slice of pizza becomes a whole pizza!
