  • Battery

    In the 1800, Volta created what seems to be the closest example to how a modern day battery worked. That battery was made by piling up layers of silver, paper or cloth soaked in salt, and zinc. Many triple layers were assembled into a tall pile, without paper or cloth between zinc and silver, until the desired voltage was reached. Even today the French word for battery is ‘pile'
  • Camera

    Joseph Nicéphore Niépce was the first person to take a photograph. He took the picture by setting up a machine called the camera obscura in the window of his home in France. It took eight hours for the camera to take the picture.
  • The Sewing Machine

    The Sewing Machine
    The first functional sewing machine was invented by the French tailor, Barthelemy Thimonnier. His machine used only one thread and a hooked needle that made the same chain stitch used with embroidery.
  • The dishwasher

    The dishwasher
    The first dishwasher was invented in 1850 by Joel Houghton.The machine was made of wood and for it to function, you had to hand-turn a wheel that caused water to splash on the dishes. However, his machine wasn't very effective at dish-washing. The first practical dishwasher was invented by a woman named Josephine Cochran in 1886. Dishwashers, however, did not begin appearing in homes until the 1950s.
  • Bunsen burner

    Bunsen burner
    The bunsen burner was named after the man who invented it, Robert Wilhelm Bunsen. He invented the Bunsen burner for his research in isolating chemical substances. This invention, now a widely common equipment to have in a lab, has become one of the most vital inventions ever to have been invented for labratorial uses. The bunsen burner is used to heat substances, such as liquid, to perform orderly experiments, and is the main source of heat in a lab.
  • Typewriter

    The first practical and modern typewriter was invented by Christohper Scholes. His goal originally was to invent a machine which was able to print his thoughts twice as fast as he could write them, with the compactness and neatness of print. His machine was the first typewriter to be commercilly successful. Befor that, in 1852, american inventor John Jones invented a slow but good typewriter, which he gave the name: the mechanical typographer.
  • The telephone

    The telephone
    The telephone is a communication device that runs on wires and electricity. It was invented to enable two people to communicate over long distances by voice. Before we had cordless mobile phones, telephones were only able to send signals though wires. In the olden days, letters were the mainly the only way to communicate over long distances, before Edison found a new way to do this.
  • Cash Register

    Cash Register
    When the cash register was invented, James Ritty nicknamed his invention the “incorruptible cashier”, and started the National manufacturing company to sell them. During each sale, a paper tape was punched with holes so that the merchant could keep track of sales (at the end of the day, the merchant could add up the holes). John H. Patterson improved Ritty's cash register by adding a paper tape that kept a printed record of all transactions.
  • The electrical iron

    The electrical iron
    The electric iron was invented in 1882 by Henry W. Seeley. Seeley invented his "electric flatiron" on June 6, 1882. His iron weighed almost 15 pounds and took a long time to warm up.
    Other electric irons had also been invented, including one from France (1882), but it used a carbon arc to heat the iron, a method which was dangerous.
    Nowadays, we have cordless irons which charge up without the need of any wires.
  • The escalator

    The escalator
    An escalator is a moving stairway that helps people move easily from one floor to another in building. It has a similar intention to the elevator, except it can hold more people at the same time (and you never had to waste your time waiting for one). The escalator was invented by the American inventor Jesse W. Reno. The original version of the first escalator had a stationary handrail, which was then replaced later with a moving handrail.
