Electric Charge Demonstration

Everything contains particles which have electrical charges, they can be positive, negative or neutral. Atoms are the basic building blocks of everything in the universe, and are made up of three components, electrons, protons and neutrons.   Electrons have a negative electric charge and are usually associated with electricity. Protons have a positive electric charge … Continue reading Electric Charge Demonstration

Lord Kelvin’s Thunderstorm

Lord Kelvin’s Thunderstorm is a type of electrostatic generator invented by British scientist William Thomson, better known as Lord Kelvin, in 1867. Kelvin referred to the device as his water-dropping condenser.   The device uses falling drops of water to generate voltage differences by using electrostatic induction, which occurs between interconnected, oppositely charged systems.   … Continue reading Lord Kelvin’s Thunderstorm

Melting a Penny With a Car Battery

Most people are under the impression that pennies are made of copper. This is only partially true. Before 1982, pennies were made of 95% copper and 5% zinc. Because the price of copper was rising, the U.S. Mint had to change the penny’s composition to keep the cost of the coin under one cent.   … Continue reading Melting a Penny With a Car Battery
