An elephant, who accidentally fell into a dry, 25-foot deep well in Northeast India, lived to see another day thanks to the quick-thinking rescuers' scientific knowledge. The chain of events unfolded early in the morning on Tuesday, January 28, 2020, when citizens of Amliya toli village, in the state of Jharkhand, awoke to the cries of the trapped animal and called the forest department for help.

When the rescuers arrived, they instantly realized that pulling out the huge animal, which seemed to be about 30 years old, was not a practical idea. Fortunately , the forest department officials had been paying attention in their science class and were well aware of the Archimedes' principle. The physics law of buoyancy(浮力),which explains how ships stay afloat, states that when a body is partially or fully immersed in a liquid, it experiences an apparent loss in weight that is equal to the weight of the liquid displaced by the part of the body in the liquid.

In this case, that meant filling the well with enough water to displace the elephant's weight. It took the three motorized pumps over three hours to add the hundreds of gallons needed to enable the heavy animal to float up to the surface. However, it was well worth the effort. A heart-warming video shows the villagers cheering as the animal, using the makeshift ramp (斜坡)dug by the rescue team, pulls itself out of the well and walks away to safety in the nearby forest.
