How does lightning form and why is it dangerous?

Lightning is when clouds get really angry and throw out super-fast electricity.

What makes lightning happen

Clouds are full of tiny water droplets and ice crystals. When they move around, they bump into each other like kids in a playground. This pushing and shoving causes electric charges to build up, one side of the cloud becomes positive, and the other becomes negative.

The ground below also gets involved. It acts like a big magnet, pulling the negative charge from the cloud down toward it. This makes a kind of electric “road” between the cloud and the ground, like a path for electricity to travel on.

When the charges get strong enough, BOOM!, lightning happens! The electricity jumps from the cloud to the ground in a flash, like a giant spark from a battery.

Why lightning is dangerous

Lightning is super hot, about 5 times hotter than a stove on high. If it hits you, it can feel like being zapped by a giant toaster. It also moves really fast, faster than your favorite cartoon character running away from a monster!

If the electricity goes through your body, it might give you a big shock or even hurt you. That’s why we should stay safe during storms and avoid touching things that can conduct electricity, like metal fences or puddles.
