It seems some people are putting all my stuff in Pinterest. You may think I'm gonna scold you, but in fact I appreciate it A LOT. Thank you guys. Seriously. Just remember to link to this site, we could really use the extra popularity. Thanks a lot, again...

Static Electricity- Kids LOVE it

Learn about static electricity with these 3 simple, fun science projects.

SAFETY NOTE: Please read all instructions completely before starting the projects. Observe all safety precautions.

  • Electrical Charge
• Learn More
  • Follow Those Electrons - the Triboelectric Series
  • Electric Fields - Coulomb's Law
• Easy Reading
• Projects

Tip: Try to use the part of the charged object that has the biggest charge (the part that was rubbed the most) when doing these experiments. Also, Projects 1-3 work best on dry days.

Project 1 - Swinging cereal

What you need:

• a hard rubber or plastic comb, or a balloon
• thread, small pieces of dry cereal (O-shapes, or puffed rice of wheat)

What to do:

1. Tie a piece of the cereal to one end of a 12 inch piece of thread. Find a place to attach the other end so that the cereal does not hang close to anything else. (You can tape the thread to the edge of a table but check with your parents first.)
2. Wash the comb to remove any oils and dry it well.
3. Charge the comb by running it through long, dry hair several times, or vigorously rub the comb on a wool sweater.
4. Slowly bring the comb near the cereal. It will swing to touch the comb. Hold it still until the cereal jumps away by itself.
5. Now try to touch the comb to the cereal again. It will move away as the comb approaches.
6. This project can also be done by substituting a balloon for the comb.

What Happened: Combing your hair moved electrons from your hair to the comb. The comb had a negative static charge. The neutral cereal was attracted to it. When they touched, electrons slowly moved from the comb to the cereal. Now both objects had the same negative charge, and the cereal was repelled.

Project 2 - Bending water

What you need:

• a hard rubber or plastic comb, or a balloon
• a sink and water faucet

What to do:

1. Turn on the faucet so that the water runs out in a small, steady stream, about 1/8 inch thick.
2. Charge the comb by running it through long, dry hair several times or rub it vigorously on a sweater.
3. Slowly bring the comb near the water and watch the water "bend."
4. This project can also be done by substituting a balloon for the comb.

What Happened: The neutral water was attracted to the charged comb, and moved towards it.

Project 3 - Light a light bulb with a balloon

What you need:

• a hard rubber or plastic comb, or a balloon
• a dark room
• fluorescent light bulb (not an incandescent bulb)

SAFETY NOTE: DO NOT USE ELECTRICITY FROM A WALL OUTLET FOR THIS EXPERIMENT. Handle the glass light bulb with care to avoid breakage. The bulb can be wrapped in sticky, transparent tape to reduce the chance of injury if it does

What to do:

1. Take the light bulb and comb into the dark room.
2. Charge the comb on your hair or sweater. Make sure to build up a lot of charge for this experiment.
3. Touch the charged part of the comb to the light bulb and watch very carefully. You should be able to see small sparks. Experiment with touching different parts of the bulb.
4. This project can also be done by substituting a balloon for the comb.

What Happened: When the charged comb touched the bulb, electrons moved from it to the bulb, causing the small sparks of light inside. In normal operation, the electrons to light the bulb come from the electrical power lines through a wire in the end of the tube.

It's good. Better than ours, really.

Sorry for not putting anything in the blog...

I started this blog just for fun, and I never thought that so many people would visit my blog. So here's sorry for not posting anything new in a while, and also my promise I'll get this thing all active again. To motivate me and ensuring that I keep putting stuff here, send me an e-mail at hellotohitesh@gmail.com. Every letter gets me more, uh, dedicated, I guess. Lol

Vibrating Coin

Vibrating Coin

Aim:

To demonstrate the expansion of air when heated.

Materials Required:

1. Coin 2. Bottle

Procedure:

Place an empty bottle in a refrigerator to cool it. When the bottle is cold remove it and put a coin on the opening as shown. Then dip your finger in water and place a few drops around the edge of the coin to seal the opening. Then place both your hands around the bottle, holding it firmly for about fifteen seconds. The coin will start to click up and down. Let it vibrate for a while, then remove your hands. The coin goes right on vibrating ! This shows the illustration of how air expands when heated. The cold air inside the bottle is warmed by the heat from your hands and the expanding air escapes around the rim of the coin causing it to vibrate.

Anti gravity machine

PROJECT TITLE:

Anti-Gravity Machine

Aim:

To make an Anti-Gravity Machine

Materials Required:

1. Two plastic funnels 2. Cardboard 3. Adhesive cement

Procedure:

To make an Anti-Gravity Machine that seems to work against gravity. When the machine placed at the bottom of a sloping track, it appears to run uphill against gravity. The machine is a double cone, easily made from two plastic funnels. Use adhesive cement to stick their rims together. The sloping track is cut from cardboard, which has to be adjusted to get the slope just right, since the gradient will depend on the size of the funnels. Place the track so the two sides are about an inch apart at the lower end, with a width at the other end equal to the length of the double funnels. When the funnels are placed at the bottom of this track, it rolls to the top. This is because as the funnels appear to move up, the increasing width of the track lowers the funnels so that its centre of gravity actually becomes lower.
