- A Solar Battery

Use pn-junctional semiconductors which convert the radiant energy of sun light into electric power. If sun light's blocked a solar battery doesn't work as a battery because it can't store electric power.

- A Discharge Ladder

Discharge is a phenomenon that the electricity flows the positive and negative poles. It induces the movement of electric power and has come in forms of light and heat. To demonstrate charge flow in air, and how ionized air rises with respect to its surrounding air. Electric discharge climbs with rising ionized air.

- A racing of steel bulbs

There are electromagnets on the 5 parts of an endless track. Push an accelerator button and send an electric current when the steel bulb reach in the electromagnets. Then the motion of steel bulbs accelerates and the steel bulbs race on the rail faster and faster.

- LASER Holography

The basic principles of LASER and holograms, which incorporate photographic plates with a three-dimensional record of the interference pattern, are illustrated by diagram and an experimental apparatus.

- A Magnet Gear

This shows a basic principle of a magnet using familiar tools. The Magnet has repulsion and attraction so they push and pull each other.

- Drawing a picture in the mirror

Draw a star reflected in a mirror. It is hard to finish the drawing. But practice it repeatedly, you can make fewer errors and draw it faster. This shows our sense can be changed though experience.

- The Transmission of Power

The equipment of the transmission of power are composed of cam, plate, gear, etc. Gear is working by the motion of motor and through each equipment of the transmission of power a simple rotary motion is changed to a straight reciprocating motion or rotation of gear.

- Monochromatic Light

Understand the characteristics and principles of laser using various figures by laser. Laser is initials of Light Amplification by Stimulated Emission of Radiation.
It is a singular wavelength and monochromatic light in the same rank.

- Natural Light

Mixture of visible rays and infrared rays and ultraviolet rays which are invisible.

- Exciting Volleyball Game

Test your agility.
Who can press the colored buttons faster in a moment?

- Motion of Steel Bulbs

Observe the motion of steel bulbs moving in the rails. Observe the changes in speed and motion. An object which in a particular height has potential energy and if the object goes down, potential energy changes into kinetic energy.

- Drifting Rings

Actual rings stick together but they look like spinning separately because of an optical illusion.

- Air Bubble

When you move a handle of an air pump up and down the compressed air goes up in the transparent tube. The air bubble generated in the bottom of the tube filled with liquid(paraffin) is crushed because of pressure from all directions. But when it goes up by buoyancy, size of the air bubble is getting bigger. Because pressure from the liquid(paraffin) decreased.

- The Floating Globe

When light from a light source reaches in a light sensor an electromagnet is operating. If the globe is closed to the electromagnet, it screens the light and the electromagnet stops working. So the globe falls. But when the globe falls, light reaches in a light sensor and the electromagnet is functioning again and attracts the globe again. So the globe floats in the position that gravity and power of an electromagnet keep their balance.

- A Spinning Egg

Put a metal egg in the magnetic field it spins because of an eddy current by an electromagnet.

- Specific gravity of a Fluid

Effect of liquid paraffin and centrifugal separation of water.

- A Hand Boiler

Put diethyl ether solution in an airtight container and heat the solution with body heat. Then the solution boils and moves up. Because diethyl ether solution has low boiling point.

- A Magic Mirror

Make an object visible and invisible using the properties of semipermeable mirror and controlling luminous flux.

- A Complicated Question

When you make the tap water runs well you have to connect pipes. To make electricity flows you have to connect cables. Electricity flows many different directions connecting cables is more complicated than connecting pipes.

- Principles of Nuclear Generation

This exhibition explains principles of nuclear generation using 3D and is organized as the form of story telling for children.

- Stamp Robot

How to use
¨ç Put a paper under the stamp.
¨è Let down the stamp.
¨é The stamp goes up.

- Robot

We call a robot a man-made man. Robot is an automaton set the machine in the human-shaped figure and moves the other parts just like a man. The word robot refers to 'robota' which means work in Czech.
