In good old days, all wrapping paper used to be made of paper. Nowadays, you can get wrapping material that is made of very thin plastic. Some of this plastic material has a reflective silver covering. Perhaps you’ve received a birthday gift wrapped in this reflective material? If so, what did you do with the

An electroscope is used to detect the presence of electric charges, to determine whether these charges are positive or negative, and to measure and indicate their intensity. By the help of this electroscope we will see the movement of electrons.Things Required:Aluminium foil, as thin as possibleGlass jar, 1 qt. (1 litre)Soft plastic lid to cover

“Never use an electric appliance while you are in the bathtub!”Although it is not a great conductor of electricity, water can easily conduct the current that flows from the power outlet of your home. The results are often deadly.What about static electricity? Can water interact with non-moving charges?Things Required:Plastic combPencilPlastic penA piece of woolSinkDirections:Turn on

Fun house mirrors can reflect some pretty strange images. Look into one mirror and your body might appear 10 feet tall. Walk in front of another mirror and you might look as if you didn’t have a mid-section. These kinds of distortions are produced by curves.Things Required:Shiny metal tablespoonDirections:Hold up a shiny metal tablespoon. Note

In this experiment, we will use simple material which is easily available in every home to charge an object with static electricity.Things Required:Comb, Tissue paper, Scissors, RulerDirections:Cut a strip of tissue paper about 3 inches × 10 inches (7.5 cm × 25 cm). Cut long, thin strips in the paper, leaving one end uncut (see

Only by feeling for an opening can you navigate through this maze of mirrors? In this experiment, you’ll build a much smaller,

The galvanometer is an instrument for measuring small electric currents by the deflection of a moving coil. In this experiment, we will make a galvanometer and determine if an electric current affects a magnet.Things Required:Aluminium foil, 1 yd. (1 m)CompassCardboard box to fit the compassScissorsD-cell batteryDirections:Cut a piece of aluminium about 36 inches × 24

The magician covers a box with a silk scarf. Slowly, she raises the box into the air. While holding the covered box, she suddenly flicks her wrist. The scarf goes limp and the box disappears. How did she do it? We’re not telling, but we do have a magical activity that also produces a phantom
