Bird in a Cage is a very popular toy used during the Victorian times called a Thaumatrope.

The scientific principle behind this toy is known as "persistence of vision."

The Thaumatrope fools your eye by switching images faster than the tenth-of-a-second limit, thus merging what are in fact two separate images into one visual impression.

     POP GUN

A pop gun  is a toy gun that uses air pressure to fire a small tethered or untethered projectile (such as cork or foam) out of a barrel.

The sound made by the gun is due to Air pressure which forces the Cork out of the barrel of the gun with a Pop!


In Magic Milk you will be able to observe examples of changes in substances.

Liquids like water and milk have a property known as surface tension. If you look closely at the edge of the surface of water in a clear glass, the water appears to rise up the side of the glass because the surface tension of the water is actually pulling the water away from the glass inward toward the center of the surface. Since milk is mostly water, it has surface tension like water.


Magnetic car works on the basic principles of magnetism.

The car is moved by the attraction and repulsion properties of a magnet.


A Magnet is any object that has a Magnetic field. It attracts ferrous objects like pieces of Iron, Steel, Nickel and Cobalt.

The repulsive property of magnets cause the frog to jump.




Magnetic maze

This activity will increase the puzzle solving skills of kids.

Help understand the concepts of Magnetism.

Differentiate between magnetic and non-magnetic materials.


Chaos Theory is the scientific theory that a single occurrence, no matter how small, can change the course of the universe forever.

The butterfly effect is a term used in Chaos Theory to describe how small changes to a seemingly unrelated thing or condition (also known as an initial condition) can affect large, complex systems.


This activity helps students to better understand Jet Propulsion. Balloon Car uses Jet power to propel itself. The stored air in the balloon pushes through the straw, creating Thrust - the force that pushes the car forward. So when air from the balloon moves in one direction, it pushes the car in the opposite direction.


Grab a pencil, pull on your thinking cap and get ready to solve some of the most baffling brain-benders ever.

This activity will test your anagram skills 


Helicopters are "rotary wing aircrafts," meaning that the rotor which is turned around rapidly by the engine(s) is shaped like a narrow wing and provides the  Lift necessary to overcome the Weight of the aircraft. This is different than a "fixed wing" aircraft where the wings are attached to the fuselage (fixed) and the Thrust of the engine(s) moves the plane forward to generate Lift. Tilting the rotor allows the helicopter to move forward and backward or side-to-side.







This experiment provides a fun way for kids to witness magnetism in action while having fun. It helps concepts such as invisible forces like magnetic fields to be understandable for kids while peaking their interest about science.


Proper task lighting is a very important and often overlooked aspect of any room or work environment. This activity will explain the importance of proper lighting and how light travels.


A windmill is a machine that converts the energy of wind into rotational energy by means of vanes called sails or blades.The reason for the name "windmill" is that the devices originally were developed for milling grain for food production; the name stuck when in the course of history, windmill machinery was adapted to supply power for many industrial and agriculturalneeds other than milling.


A hovercraft, also known as an air-cushion vehicle or ACV, is a craft capable of travelling over land, water, mud or ice and other surfaces both at speed and when stationary. Hovercraft are hybrid vessels operated by a pilot as an aircraft rather than a captain as a marine vessel.


A sundial is a device that tells the time of day by the position of the Sun. As the sun moves across the sky, the shadow-edge aligns with different hour-lines. All sundials must be aligned with their styles parallel to the axis of the Earth's rotation to tell the correct time throughout the year. 


In this activity students will learn how circuits work and will also design and build a Simple Circuit. Electrical circuit is an electrical network that has a closed loop giving a return path for the current.


Quizboard is a quiz game best described as Words with Friends meets Trivial Pursuit. You answer trivia from categorical questions, and use your strategic skills to advance on the game board. You can play Quizboard with your friends, or with random opponents, but don’t be fooled by its easy-to-use features and intuitive interface. Quizboard may be easy to learn, but it’s hard to master… and a LOT of fun to play.


A fire alarm system is a set of electric/electronic devices/equipment working together to detect and alert people through visual and audio appliances when smoke/fire is present. These alarms may be activated from smoke detectors, heat detectors, water flow sensors, which are automatic or from a manual fire alarm pull station.


A kaleidoscope is a cylinder with mirrors. As the viewer looks into one end, light entering the other creates a colorful pattern, due to the reflection off of the mirrors. It was created in 1817 by Scottish inventor Sir David Brewster.It operates on the principle of multiple reflection, where several mirrors are placed at an angle to one another (usually 60°).                                                                      



Components of an electrical circuit or electronic circuit can be connected in many different ways. The two simplest of these are calledseries and parallel and occur very frequently. Components connected in series are connected along a single path, so the same currentflows through all of the components. Components connected in parallel are connected so the same voltage is applied to each component.A circuit composed solely of components connected in series is known as a series circuit; likewise, one connected completely in parallel is known as a parallel circuit.


An optical fiber (or optical fibre) is a flexible, transparent fiber made of high quality extruded glass (silica) or plastic, slightly thicker than a human hair. It can function as a waveguide, or “light pipe”, to transmit light between the two ends of the fiber. Power over Fiber (PoF) optic cables can also work to deliver an electric current for low-power electric devices. The field of applied science and engineeringconcerned with the design and application of optical fibers is known as fiber optics.


A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. PCBs can be single sided (one copper layer), double sided (two copper layers) or multi-layer. Conductors on different layers are connected with plated-through holes calledvias. Advanced PCBs may contain components - capacitors, resistors or active devices - embedded in the substrate.



The hovercraft was invented by Christopher Cockerell in 1956. The theory behind one of the most successful inventions of the 20th century, the Hovercraft, was originally tested in 1955 using an empty KiteKat cat food tin inside a coffee tin, an industrial air blower and a pair of kitchen scales. Sir Christopher Cockerell developed the first practical hovercraft designs, these led to the first hovercraft to be produced commercially, the SRN1.


Chemical energy stored in different substances can be converted to electrical energy. This ability is the foundation of design of all batteries. Each battery has two poles usually made of two different metals. One pole is the positive pole and the other is the negative pole. Electrons can travel from negative pole to the positive pole via a conductor such as a wire.A flow of electrons in a conductor is called electricity and if large enough, it can be used to make electro magnet, light up a light bulb or run an electric motor. Inside each battery there are chemicals that cause such chemical reactions. These chemicals in general are called electrolytes. 


An electromagnet is a type of magnet in which the magnetic field is produced by electric current. The magnetic field disappears when the current is turned off. Electromagnets are widely used as components of other electrical devices, such as motorsgeneratorsrelays,loudspeakershard disksMRI machines, scientific instruments and magnetic separation equipment, as well as being employed as industrial lifting electromagnets for picking up and moving heavy iron objects like scrap iron.


A galvanometer is a type of sensitive ammeter: an instrument for detecting electric current. It is an analog electromechanical actuator that produces a rotary deflection of some type of pointer in response to electric current flowing through its coil in a magnetic field.Galvanometers were the first instruments used to detect and measure electric currents. Sensitive galvanometers were used to detect signals from long submarine cables, and to discover the electrical activity of the heart and brain.


Electroplating is a process that uses electrical current to reduce dissolved metal cations so that they form a coherent metal coating on anelectrode. The term is also used for electrical oxidation of anions onto a solid substrate, as in the formation silver chloride on silver wire to make silver/silver-chloride electrodes. Electroplating is primarily used to change the surface properties of an object (e.g. abrasion and wear resistance, corrosion protection, lubricity, aesthetic qualities, etc.), but may also be used to build up thickness on undersized parts or to form objects by electroforming.
