Bending Water with Static Electricity

Bending Water with Static Electricity When two objects are rubbed against each other, some of the electrons from one object jump to the other. The object that gains electrons becomes more negatively charged; the one that loses electrons becomes more positively charged. The opposite charges attract each other in a way that you can actually see. One way to collect charge is to comb your hair with a nylon comb or rub it with a balloon. The comb or balloon will become attracted to your hair, while the strands of your hair (all the same charge) repel each other. The comb or balloon will also attract a stream of water, which carries an electrical charge. Difficulty: EasyTime Required: minutes What You Need Aside from water, all you need for this experiment is dry hair and a comb. The trick is using a comb that picks up charge from your hair. Choose nylon, not wood or metal. If you dont have a comb, a latex balloon works equally well. Water faucetNylon comb or latex balloon Heres How Comb dry hair with a nylon comb or rub it with an inflated latex balloon.Turn on the tap so that a narrow stream of water is flowing (1 to 2 mm across, flowing smoothly).Move the balloon or teeth of the comb close to the water (not in it). As you approach the water, the stream will begin to bend toward your comb.Experiment!Does the amount of bend depend on how close the comb is to the water?If you adjust the flow, does it affect how much the stream bends?Do combs made from other materials work equally well?How does a comb compare with a balloon?Do you get the same effect from everyones hair or does some hair release more charge than others?Can you get your hair close enough to the water to repel it without getting it wet? Tip This activity will work better when the humidity is low. When humidity is high, water vapor catches some of the electrons that would jump between objects. For the same reason, your hair needs to be completely dry when you comb it.

Tibetan Situation Getting Sticky

Tibetan Situation Getting Sticky Tibetan Situation Getting Sticky Tibetan Situation Getting Sticky By Maeve Maddox I was startled to read the following in an article by Associated Press writer Christopher Bodeen: But China has angrily rejected all calls for dialogue, and Tibets hardline Communist Party chief [Zhang Qingli ] was quoted Wednesday in a particularly viscous attack on the Dalai Lama The quotation left me picturing His Holiness covered with something like tar, awaiting the application of feathers. Bodeen probably meant vicious. vicious [vishus] bad, villainous, reprehensible, mean, depraved, noxious, savage Vicious comes from the Latin word Latin vitiosus, meaning full of faults, bad, corrupt. The word viscous, on the other hand, comes from a Latin word viscosus, meaning full of birdlime. viscous [viskus] viscid, gelatinous, gluey, sticky. Syrup is viscous. Oil is viscous. (No oil in Tibet.) While were at it, birdlime is a sticky substance smeared on a surface with the intention of catching birds. It was usually made of holly bark, but mashed up mistletoe berries work. The lime in birdlime comes from a Latin verb meaning to smear. The Bodeen article goes on to say that the Chinese government regularly insults the Dalai Lama as a matter of policy: Critics say China fuels such anger [as provoked the recent demonstrations] through harsh restrictions on Tibetan culture and Buddhism - including routine vilification of the Dalai Lama, who is deeply revered by most Tibetans. Which brings us to another V word. vilification The action of vilifying by means of abusive language. Want to improve your English in five minutes a day?
