121 Plus 9 Physics Experiments

You might have seen some of the popular 3-D movies like “Chota Chetan”. Wow! That guy jumped right out of the screen! How did they make those 3-D effects? If you tried to remove your viewing glasses, you probably were disappointed. The movie looked out of focus. Actually, there were two movies which were projected […]

Can you find the magnetic north pole by the help of an apple or a tennis ball? In this easy experiment we will show you how you can do it.Thing Required:Apple or tennis ballDirections:Hold the apple in your right hand, and assume it is the earth, spinning on its axis. Wrap your fingers around the

S….0 … S. As the Titanic sank, its radio officer sent out this distress call. Each click of the Morse code’s key temporarily closed an electric circuit. This circuit produced a spark, which created an invisible energy wave that travelled out from the sinking ship. These waves were detected by the antennae of other boats.

Cellophane tape is allway sticky. But in this experiment, it seems to behave odd. In this experiment, we will understand more about the effect of static electricity.Things Required:Cellophane tape Directions:Press two pieces of tape onto a table, leaving a small piece hanging over the edge. Hold the ends of the tape and quickly pull both

Have you ever tried to separate clothes that were just taken out of a drier? If so, you most likely encountered static cling. As the clothes were tossed in the drier, the materials rubbed against one another and transferred charges. Clothes that became opposite charged stuck together.Things Required:Silk shirtWoollen sweaterMirror Directions:Put on a silk shirt.

For our next trick, we are going to make one million rupees appear from nowhere! Sorry, we are mistaken. Due to tax laws, we won’t be able to work with such a large sum of money. We will, however, make a hidden coin magically reappear.Things Required:Opaque soup bowl or mugWater-filled cupCoin Directions:Place a coin in

The purpose of this neat experiment is to demonstrate attracting and repelling forces between objects due to their electrical charges.Things Required:2 round balloons, 9 inches (23 cm)Masking tapeString, 2 yd. (2 m)Clean, dry, oil-free hairMarking penDirections:Inflate both balloons and tie their ends. Use the marking pen to label one balloon A and the other B.Cut

In this experiment, you will find something shocking and snapping.Things Required:Wool rugMetal doorknobDirections:Find a room that has a rug and a metal doorknob. Turn off all the lights and pull down the window shades. Put on your shoes and walk across the rug to the door.Slowly bring your index finger towards the doorknob. What did

Smoke and mirrors. For centuries, this phrase was the magician’s hallmark. It was believed that most stage illusions were accomplished with the aid of these tools. One of the more popular tricks of the 1800s was making your assistant disappear and reappear at will. Although we won’t tell you how it was done yet you

Do static charges produce sound? This is what we are going to find out.Things Required:Large paper clipPiece of woolA scarf, coat or sweater made of 100% wool will workClear plastic sheetScissorsModelling clay Directions:Cut a plastic strip about 1 in. × 8 inches (2.5 cm × 20 cm). Use the clay to stand the paper clip

Sometimes, static electricity experiments work great. Other times, they seem to fizzle out. Here’s an experiment that will help you explore how your surroundings affect static charge.Things Required:BalloonBathroom Directions:Find a bathroom with a shower or bathtub. Make sure that no one has bathed in the room for several hours. The air in the room should

The idea behind this experiment is to demonstrate the effect of static electricity.Things Required:CombAluminium foilScissorsDirections:Cut ten tiny pieces of aluminium foil and lil them on a table. Quickly, move the comb through your hair. Your hair must be clean, dry and oil-free. Hold the teeth of the comb above the foil pieces. Do not touch

Electrical charges flow easily through metal. Yet, we haven’t used metal in any of the experiments. Why? Because there is a problem while using metal. Unlike materials such as plastic, paper, and nylon-metal is not lightweight. It’s heavy. The mass of metal can easily “mask” the attraction of electrostatic forces. But for those of you
