  2. Luc,

    Please tell me where you got your information. I think you found it at wikkianswers and what they say is that "Georges bunnot is a famous man for building candles". Does this mean that he invented them? Please read information carefully. Can we always rely on and trust all web sites?

  3. Thomas Alva Edison invented the light bulb.


  4. Why are rainbows made of different colours?

    A rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere. They take the form of a multicoloured arc, with red on the outer part of the arch and violet on the inner section of the arch.
