Chakram is a circular throwing weapon that looks like a circle or a ring. It is used in India and other countries as a weapon, but also as a sport or a hobby.
Imagine you have a plastic ring that you can throw like a toy frisbee, but it comes back to you like a boomerang. That's kind of what a chakram is like, except it's made of hard metal and is meant to be thrown at people or targets.
To use a chakram, you hold it by the hole in the center and spin it around your finger. Then, when you want to throw it, you flick your wrist and release it like you would release a frisbee.
The chakram can be very dangerous because it is sharp and can cut into people or animals. So it is not a toy and should only be used by people who are trained and responsible.
But for those who enjoy practicing with chakrams, it can be a fun and challenging sport. Some people even compete in chakram contests to see who can throw it the farthest or hit the most targets.
