What are knockouts?

A knockout is when something happens so fast and strongly that it completely stops what was going on before, like a surprise punch in a boxing match.

Imagine you're playing with your toy cars on the floor. You line them up, ready to race. But just as you say "go!" someone sneezes really loudly right next to you. Boom! All the cars fall over, and no one can even hear the sound of the engines anymore. That sneeze was a knockout, it stopped everything else in its tracks.

Like a Surprise Stop

In science or medicine, a knockout is when a person or animal suddenly loses consciousness, like being hit by a big wave while swimming and then falling asleep under the water. It’s not because of magic, but because something strong and fast happened to them, just like that sneeze knocked everything out of place.

Knockouts can be fun, like in sports, or they can be surprising, like when you're reading a book and suddenly feel like you've been hit by a train.
