Singing pipes

Sound of different musical notes are emitted by hitting the various pipes in the exhibit. The frequency or pitch of the sound depends on the length of the air column in the pipes. The shorter the length of air column, the higher is the pitch.


Eye as an Aperture

This exhibit demonstrates that eye pupil diameter becomes larger or smaller when light intensity is low or high respectively like an aperture of a camera

Stereo hearing

The exhibit demonstrates that our ears can detect the direction of sound even if the time difference between the sounds reaching either of the ear is as low as 1/2000th of a second. If the sound arrives at both ears at exactly the same time, we interpret the sound as coming from either in front or behind us.

Explore Light

Is Light Visible?

This exhibit demonstrates that light is a form of energy that makes things visible when it falls on them but by itself it is invisible.


Transfer of Momentum

The exhibit demonstrates in an interesting way the principle of transfer of momentum by a group of seven hanging balls.


Swing the Pendulum


Sympathetic Swing (X, Y & Z -Axis)

This exhibit consists of three sets of two pendulums each. It demonstrates as to how the motion of the first pendulum is transferred to the second through the connecting strips/springs. When the oscillation of second pendulum is just in opposite phase to that of the spring, it stops and when it is in the same phase, it has maximum swing.



This exhibit demonstrates that the oscillations of the pendulums with bobs of asymmetrical shape create unpredictable oscillatory movement and therefore do not follow the rules of simple harmonic motion.

Curie Point

The exhibit demonstrates the principle of curie point of the material i.e., the temperature at which magnetic material undergoes structural change to become non-magnetic


Grand shuttle

The exhibit demonstrates the repulsion property of electromagnets formed by energising the coil through a foot switch. When a person walk over the switch, it energizes a coil due to which upper end of the coil and the lower end of the bobbin gains same polarity thereby repelling each other resulting in movement of the shuttle to the other end.

Lazy Channel

The exhibit shows that a magnet rolling along aluminum channel, which acts as a single turn coil, induces a strong short- circuiting current in it. This current gives rise to another magnetic field, which opposes the field of the rolling magnet, thereby slowing down its downward movements.
