Arvind Gupta is a toy inventor and populariser of science. "Gupta began his social service by teaching the children of the mess staff who had no opportunities for formal education he developed his idea of creating simple toys and educational experiments using locally available materials as well as items usually thrown as trash. These simple toys, he found, fascinated children and Gupta went on to make these as the hallmark of his movement of popularising science.
