An anti-handling device is like a booby trap that is put in place to prevent people from tampering with dangerous things like bombs or explosives. Just like how you might set up a mousetrap to catch a pesky mouse, anti-handling devices are designed to catch anyone who tries to mess with something they shouldn't.
These devices work by activating when someone tries to move or touch the object that it is protecting. This could happen if someone is trying to disarm a bomb, for example. When the device is triggered, it might set off an alarm or a loud noise to warn everyone nearby that something dangerous is happening. It could also cause the explosive to detonate, which could be very dangerous for anyone in the area.
So, think of an anti-handling device like a warning sign that says "stay away" or "dangerous" - it's there to protect you and others from harm. Just as you shouldn't touch a hot stove, you shouldn't touch things that might have an anti-handling device on them. It's important to listen to warnings and stay safe!
