Thunder is sound so it travels at a speed of 343 metres per second. Lightning is 'light' so it travels at 300,000,000 metres per second.
If you count the seconds from the flash of lightning until you hear thunder, then take that number and divide by 3 = storm distance away in kilometres.
When lightning strikes, run for cover, as its 20,000 volts and could be lethal! Voltage lethal at 200 volts if skin wet and 20,000 volts if dry.
The survivable limit is 27,000 volts for a large heart.
Only 10% strikes are fatal, most injuries are caused by the extreme heat.
The temperature of a lightning bolt is 5 times hotter than the surface of the Sun!
Around the Earth there are about 100 lightning strikes per second.
The fastest speed a falling raindrop can hit you is about 30 kilometres per hour.
Keep away from water and open spaces during a thunderstorm!
