The street ‘Kalaiwala’ gives shining appearance by rubbing a shining silvery material. What is this material made up of ?

Zinc
Tin
Lead
Aluminium

The correct answer is (d). The material is made of aluminium.

Aluminium is a soft, silvery-white metal that is used in a variety of products, including cans, foil, and building materials. It is also used to make Kalaiwala, a type of street art that is popular in India. Kalaiwala is created by rubbing a piece of aluminium foil against a rough surface, such as a brick wall. The friction between the aluminium foil and the wall creates heat, which melts the aluminium and causes it to flow into small grooves in the wall. The resulting pattern is a shiny, silvery design that can be quite intricate.

Zinc, tin, and lead are all metals that are also used in a variety of products. However, they are not as soft as aluminium and are not as easily melted. As a result, they are not suitable for use in Kalaiwala.

In addition, zinc, tin, and lead are all toxic metals. If they are inhaled or ingested, they can cause serious health problems. Aluminium, on the other hand, is a relatively non-toxic metal. As a result, it is the safest metal to use in Kalaiwala.
