What is electricity?
Everything is made of atoms. At the centre of an atom is the nucleus made of protons and neutrons. An atom also has tiny electrons which spin around the nucleus. Electrons have a negative electrical charge, and protons have a positive charge. The electrons don't stay in one place. They move around to different atoms, so some atoms have more protons, some have more electrons. An atom with more protons is positively charged. One with more electrons is negatively charged. When the electrons pass from one atom to the next, it creates an electric current.

The speed will go up to 160km/h on a 2 cylinder turbo diesel engine. Another surprising part is that comes with a front wing door rather than having two side doors for the drivers to enter the vehicle.?",7.jpg,Worlds Strangest Vehicles 4108,Mattrack Truck ?the skiing car,This is a standard truck in which the wheels have been replaced by mattrack belts. The company Mattrack can apparently do this to any kind of 4?4 vehicle ? from ATVs to 20 ton trucks. The short belts allow the Mattrack Truck to drive almost anywhere unless the snow gets too deep. If the snow gets to deep, longer belts are required (like on the Piston Bully). The short belts also make Mattrack Truck able to cross small creavasses, while larger creavasses require longer belts.
