Nail bomb

Okay, kiddo. A nail bomb is a very dangerous thing that people sometimes make to hurt other people. It looks like a regular bomb with explosive materials inside, but it also has pieces of sharp metal or nails all around it.

When the bomb explodes, it sends the nails and metal pieces shooting out in all directions, like a burst of tiny bullets. This can hurt or even kill anyone who gets hit by them.

It's really important to stay away from nail bombs and tell a grown-up right away if you ever see or hear anything suspicious. They can be very, very dangerous and hurt a lot of people all at once.
