I wonder if flip flops are also used in light bulbs?...but it is not a bad idea to have one coz electronics is related to electricity and light bulb ofcourse could be related to electronics. Which means flip flops can be used in light bulbs which means more or less energy is conserved. So the law of thermodynamics is completely true. But the question still remains..how could light bulbs be if there are flip flops in it. Well flip flop is nothing more than flipping n flopping..so if it flips n flops more than a certain value so that a human eye cannot see then..bingo we have a light bulb working perfect but if it flips n flops at a slower pace then its chances that eye doctors will have quite a job to do. :D
