While playing with a metal washer shaped like a ring, Riya accidentally pushed it on her finger too far and couldn't get it off.
Trying to remove it using soap water didn't work.
The hospital sent her to a service station thinking they could cut the metal.
Since the ring was made with especially hardened steel, it couldn't be cut.
Just then Kanav arrived on the scene and suggested an easy way to remove the washer in just a few minutes.
What was his solution?
