Not golden but a silver egg!!!


1. An egg
2. A transparent glass filled with clear water
    3. A candle or a burner


1. First lite the candle or the burner or whatever can be used as a burner.
2. Then burn the egg from every side until it turns pitch black.
3. Then submerge the egg in the glass filled with water.
4. Finally watch from outside the glass.


When you watch the egg from outside the glass through the water you will see that  the black egg has turned into a silver egg.


When we burn something, a chemical reaction is caused between the burning material and oxygen in the air. Then we get carbon as a solid product. When we burn the egg shell from every side and make it totally pitch black, a thin coat of carbon covers the whole surface of the egg shell. That’s why the egg becomes black because carbon is black. In the carbon coating, some air is stuck. That’s why it (the carbon coating) do not soak. When the egg is submerged into the water, light rays hit it through the water. When the light rays reflect beck from the egg it first have to go through a dens medium (the water) and then a light medium (the air) before it can hit our eyeball i.e. retina. This change in medium with very different density causes total internal reflection of the light. When the light hits the surface of the egg it actually hits the air stuck with the carbon. This causes the total internal reflection which makes the egg look like a silver egg.


1.Use different kinds of eggs for your experiment.
