Fido explosives detector

Hey kiddo, today we're going to learn about a very special tool called the Fido explosives detector! This is a very important tool that helps us find dangerous things called explosives.

You know how when you go to the airport, there are big machines that check your bags and suitcases? The Fido explosives detector is like a smaller version of that, but it's so cool because it can sniff out dangerous things that the other machines can't!

The Fido explosives detector looks like a big flashlight with a long stick attached to it. When someone thinks there might be explosives nearby, they use the Fido to check it out. The long stick on the end is called a sensor, and it's the most important part!

The Fido detector has a very special sense of smell. You know how dogs have an amazing sense of smell? The Fido detector is like a super-dog! It has a tiny little nose inside that can detect smells that are too faint for people to smell.

When the Fido detector sniffs something, it sends a signal to the person who is holding it, telling them if it smells something dangerous or not. If it does, they can use special tools to keep themselves and other people safe!

Explosives are very dangerous things that can hurt people and damage buildings. But the Fido explosives detector helps us find them before they can hurt anyone. It's a really important tool that helps keep people safe!
