Land Mattress

A land mattress is like a special kind of bed that soldiers use to make things go boom! It's made up of a big pipe that gets filled up with gas or liquid, like gasoline. Then, the pipe gets laid down on the ground, and the soldiers light it on fire to make a big explosion!

It's kind of like blowing up a balloon, but instead of just letting the air out, we light it on fire to make it explode. This helps soldiers blow up big things, like walls or enemy bunkers.

But don't try this at home, because it's very dangerous! Only trained soldiers should use a land mattress, and they have to be very careful when they make it explode.
