On the occasion, union Human Resource Development Minister Smriti Irani said efforts were required for similar festivals in all states, and hoped a bigger attempt would be made in the capital in about six months to set the world record of 'The Largest Practical Science Lesson'.

"Hopefully, 6-7 months down the line, we would be able to make even a bigger attempt at the world record by assembling 20,000 students at the Jawaharlal Nehru Stadium in Delhi," she said while addressing the schoolchildren at the IIT Delhi.

The existing world record is held by a group of 1,339 Irish school pupils for mass chromatography practical.

Union Science and Technology and Earth Sciences Minister Harsh Vardhan and Vijnana Bharati (VIBHA) president Vijay P. Bhatkar also attended the event.

A. Jayakumar, secretary general of VIBHA, said the experiment was conducted in a glitch-free manner.

"All students conducted the experiment successfully. We will be sending the result to the Guinness Book this evening (Monday). Hopefully, the results will be declared by 12th or 13th," Jayakumar told IANS.

"It sends a message to the entire science community in the world that India can do so much more in the field of Science and Technology. It's an eye opener to the government as well. Through such attempts, students from every district in India will be excited to come forward and join science," he said.

The largest practical science lesson before this event was conducted at the Odyssey Arena in Belfast, capital city of Northern Ireland, on February 24 this year.
