In a gravity-defying stunt, a 28-year-old man spins two glasses full of water tied to a rope without spilling a drop in southern India's Tamil Nadu.

Footage from the city of Chennai on June 6 displays the surreal trick.

According to local reports, the man in the clip is Sarath Kumar, who has been training in the ancient Indian martial arts, Silambam since he was three-years-old.

Kumar fills two glasses with water and places each on a plate tied to a rope on both ends. Using the rope, he lifts the glasses and begins to swing them like a pendulum.

Following this, he twirls and swings them vigorously around his head and body without spilling a single drop of the water.

By profession, Kumar is a car driver. However, that never stopped him from mastering his agility and hand-eye coordination.

While this might appear like magic, the stunt can be explained by simple physics. Inertia, to be specific, is the resistance of an object to any change in its velocity. An inward force, despite the object moving in a circle, is what prevents water from spilling out of the glasses.

The visual came out of Chennai on June 6.

According to reports, the man identified as Sarath Kumar is trained in Silambam since he was three-year-old.

Silambam is a weapon-based Indian martial art originating in modern-day Tamil Nadu in the Indian subcontinent and is estimated to have originated in approximately 1000 BCE.

In quite a number of his movies in the 1950s and 1960s, had incorporated Silambam fighting scenes, to popularise this ancient martial art in the 20th century.

By profession, Kumar is a car driver, however, that never stopped him from practising the martial arts.

With time, he mastered the flexibility, agility, hand-eye coordination required for the craft.

The video shows Kumar filling two glasses with water and placing one each on a plate tied to a rope on both ends.

Using the rope, he lifts the glasses and begins to swing them like a pendulum.

Following this, he twirls and swings them vigorously around his head and body without spilling a single drop of the water.

Sources suggest it is a clever trick that uses physics to make sure that water stays inside the glasses as they are spun around using inertia and centripetal force
