00:00Have you ever seen this incredible metal? Apply it to a steel plate, and you can punch right through it.

00:05Drip it onto a notebook, and you can easily poke a hole in it with just your hand.

00:10Rub it onto a lock, and with a gentle twist, the lock will break.

00:15If you apply it to a tennis racket, the racket will snap in two by itself.

00:19This amazing metal is gallium, a metal that can weaken other metals.

00:24Some people doubted its destructive power, so they applied it to a fire extinguisher.

00:29Instantly, the internal gases sprayed out.

00:33In fact, gallium doesn't actually corrode metals, it alloys with them.

00:38Because gallium's melting point is extremely low, only 85.6 degrees Fahrenheit, 29.78 degrees Celsius,

00:47when you hold solid gallium in your hand, it quickly turns into a flowing liquid.

00:52But why does gallium have such a destructive effect on metals?

00:55It's precisely because of its low melting point.

00:58When it comes into contact with other metals, it seeps into them and forms an alloy,

01:03weakening the metal's original strong structure, making it brittle.

01:07So where would you want to apply it?
