From laundry soap to bath soap, everything in our house is colourful. Some are blue, some are red and some are yellow. But when the color of the soaps are different then why the color of the foam coming out of them is white. Even the foam of shampoo, face wash and hand wash is of white colour.

Why does white foam come out?
Science says about white foam that in anything there is some element of its own. There is no color, the reason behind anything that looks colorful is the rays of light. That is, the way an object absorbs the rays of light, its color appears the same. Just as an object appears black if it absorbs all the rays of light, similarly if an object reflects all the rays of light, it appears white.

Sometimes many colors are also visible in the bubbles
You must have noticed that the cloth We can see many colors on the outer layer of the big bubbles which are formed while washing, but they are visible from a very close distance, these bubbles also appear white from a distance. All this also happens due to sunlight. On the other hand, this does not happen with bath soap, the reason being that it contains wax, which does not allow large bubbles to form in the lather, and the lather of the bath soap also becomes denser, due to which it appears even whiter. is.
