Round shot

Okay, so imagine you have a little ball. This ball is made of metal and it's very heavy. Now, imagine you take this ball and put it inside a big tube that's called a cannon.

When you light the cannon, the ball gets pushed really, really hard out of the tube and goes flying through the air. This ball is called a round shot.

Round shot was used in old days by soldiers and pirates to attack enemy ships or buildings. When the round shot hit something, it could cause a lot of damage because it was heavy and flew really fast.

So, to sum it up: round shot is a heavy metal ball that was used by soldiers and pirates to attack things using cannons.
