Which kinds of toy are you willing to buy for your children?

mind creative? Look at this: 1. Experiment Name Electronic Candle 2. Experiment Purpose To know the theory of Electronic Candle. 3. Experiment Sense In this experiment you would see a spark which enlightened people to invent electricity and applied step by step in life. This experiment will tell us that the normal is not normal, it is very important to love life and thinking, Science & Technology are round of us. 10. Theory in this experiment The main element of pencil lead is carbon which is electric. Electricity meets big resistance from the air at joint part and then it reaches high temperature and make bright spark when the 2 ends kiss. Meanwhile, pencil lead releases dissociative carbon which shape carbon steam because of high temperature. When there is gap between the 2 leads, the resistance is bigger than before, but the carbon steam is still electric, so you see the electric arc light. Because we use 9V battery here, the electricity is very small, the arc light is not powerful and the temperature is low and safe to touch the leads. While practical electric candle is to give refined kryptol low voltage and high electricity for powerful light which makes the temperature high and not safe to touch. So please do not do that. This experiment is one of the original inventions, whose theory has been widely applied in our daily life, for example, fluorescent lamp.
