When it comes to toys, girls prefer fluffy, shiny, dreamy and pretty things.

Boys prefer a sense of power, because every boy has a hero dream, and powerful is attractive.For example, boys like toy guns.

I think it's not unreasonable for boys to like these toys.

I tried to play with toy guns today. The moment I picked it up, I felt very cool !However,be cool and also be safe.We have to consider whether the bullets fired by the toy gun will injure passersby or damage other things.

KE Tester is a equipment to check the speed of a object (DUT) which pass though the test tunnel .According to the result read out and mass value of DUT, we could calculate the kinetics energy value and know how danger of DUT it is.The sensor distance select is between 100 to 500mm.Inside the test tunnel of this KE tester, there are three sets of Infra-Red sensor group. One set for start the timer and other two for stop the timer.Each group include 30 pairs Infra-Red Sensor. They are located in opposite plate and the Infra-Red light are transmitter and receiver are fix in a opposite and signal will transmit and receive though a 1mm narrow gap.
