The government in China provides subsidies for the ordinary people to buy the energy saving lamps. However, these lamps all contain low content of mercury to varying degrees. The mercury can seriously threaten the environment.

Today we learned how to make flashlights. We started off by setting up our batteries in series and wiring the bottom. Then we twisted LEDS wired together and used electrical tape to separate one wire from the another to prevent a short circuit.We then wired the circuit with a button and wrapped it in some foam and covered it with tape.
Today we learned how to make flashlights form scratch. We started with simple materials such as tinfoil, batterys, a penny, Tape, and LED lights. It was fairly easy to make the entire things, took only about 20 minutes and costs less than a dollar. After we were done making it we designed it with tape.
