Good Luck.
Scientists have made the electric motor ever created. It is a feat scientific genius that most of us could never try to understand. Dr. Charles Sykes and his team from America’s Tufts University the motor from a single molecule just a billionth of a metre wide. Dr Sykes is in contact the Guinness Book of World Records to have his motor recognised as the smallest . The current world-record holder is a 200-nanometre- nano-tube made from carbon. Dr Sykes’ creation is an incredible 200 smaller. Naturally, the researchers hope their creation has for mankind. It will be used to power the tiniest machines ever built, and be by doctors in nano-surgery and robotic surgery.

It is the first time an electric has been made from a molecule. Scientists can make molecules convert from light and chemical reactions into movement, but Dr Sykes’ invention is the to be classed as a motor – something that can continually generate . There is some mind-boggling science Sykes’ device. A combination of chemicals and metals produces the miniscule motor that rotates 50 times a . Dr Sykes was excited about the of his discovery, saying: "The next thing to do is to get the thing to do that we can measure - to [link] it to other molecules, lining them up to one another so they're like miniature cog-wheels.”
