After two decades Bengaluru has organised the Southern India Science Fair (SISF), which began on January 19. Out of the 300 models presented by 600 students of the southern India states, three of them caught everyone’s eye for their out-of-the-box approach.
Of all the models, the three that caught all the attention were:
• A rescue machine for children trapped in wells
• Tsunami alert
• Waste and disposal management model
A rescue machine for children trapped in wells
Underprivileged children falling into wells have made headlines very often in the past few years. When it happened in K Sivasankari’s village, she simply had to do something about it! The Class 9 student of a government school in Villupuram, Tamil Nadu invented this rescue machine after a worker from her village slipped into a well and died.
Talking about her invention, K Sivasankari said, “When kids or labourers fall into wells in Tamil Nadu, rescuers use machines that pull out the victims by their heads. But the practice is dangerous as it can cause head injuries. I have designed the model of a machine, which can hold the person by his shoulders and minimize their risk of getting hurt.”

Bringing yet another solution to one of the other major crisis of the country was R Naveen, a Class 10 student, who designed a tsunami alert keeping in mind the vulnerability of his state to tsunami. His model will caution people living near the sea beforehand. Why a tsunami alert? “India has been battered by so many natural disasters in the past few years, including the recent Chennai floods, but no one has come up with a solution,” Naveen explains.
Waste and disposal management model
A 10th grader, Devika Prakash, from Kannur in Kerala has designed her science model to help clean the waste and disposal on the streets of the various Indian cities. As the fair was held in Bengaluru, so the girl cited example of this very city and said, “I am aware of Bengaluru's garbage woes, that's why I designed this science model. But when I arrived here and saw heaps of trash across the city, I realized what I have done is not enough.”
Her model shows how electricity could be generated from waste.
