The question that started it

Meet Srishti Asthana, determined, disciplined and committed to serving the community, whose work is going to take her to the Google headquarters in the US.

That school trip to Ludhiana, where the owner of a polluting factory asked her if people treated their detergent water at home, gave her a challenge. "Back from the trip, I decided to find a way to treat detergent powder and thought of this photocatalytic batch experiment," said Srishti.

The experiment
In her experiment, she first prepares nano particles and characterises them to make sure the size is nano. "We then add these particles to the detergent solution and irradiate it with constant stirring under sunlight for 30 minutes.

'So pure, you can even drink it'
The result is so effective that the water can be used for gardening as well as drinking," said Srishti. Experiments are still on to prove that but Srishti is positive.

Beautiful mind, kind heart
Brilliant in academics, she is also educating a poor child under 4 after winning the National Talent Search Examination (NTSE) scholarship. She plans to adopt another underprivileged child to educate.

Srishti's parents, Satish and Pooja, are confident that she will achieve all her goals and bring laurels to the country.
