An elephant gun is a very big gun that hunters use to shoot elephants. Just like how you have a toy gun that shoots little plastic bullets, the elephant gun shoots really big bullets that can stop a huge elephant.
The elephant gun is not like the guns used by police officers or soldiers to catch bad guys. Those guns are smaller and meant for short distances. Elephant guns are very big and heavy, which means they have a lot of power behind them.
Think of it like how you might have a toy car that you can push around easily with your hands, but there are also big trucks that can carry lots of heavy things. The elephant gun is like the heavy truck of guns.
But it's important to remember that hunting elephants is not good. Elephants are very important animals and we need to protect them. So, let's stick to playing with our toy guns and leave the big elephant guns to the grown-ups who need to use them for good reasons.
