2000 students from schools across New Delhi assembled took part in the event India International Science Festival (IISF) 2015. The event was jointly organised by the Ministries of Science and Technology and Earth Sciences.

A major feature of the exercise was ‘Elephant Tooth Experiment’ in which hydrogen peroxide underwent catalytic decomposition in the presence of iodide, resulting in the liberation of a large amount of oxygen and foaming up to resemble a giant toothpaste being squeezed. The other experiment was discoloration of methylene blue by hydrogen peroxide. Huge screens were set up for the students to conduct the practical. Five students each shared a table with equipments and chemicals.

The largest practical science lesson before this event was conducted at the Odyssey Arena in Belfast on February 24 this year. As per the Guinness Book of Records, 1,339 primary school students of 7th and 8th standard from Belfast participated in a mass chromatography practical. That effort was supported and conducted by The Royal Society of Chemistry, London.
