Melting a Metal Robot: Chemistry Science Experiment

Watch as Museum Educator Locke demonstrates a mind-blowing science experiment with Gally, a robot made entirely of gallium that melts before your eyes! 🤖🔥

At first glance, Gally looks like a regular shiny metal robot, but she's actually made of pure gallium—a metal with an unusually low melting point of just 86°F (30°C). That means it can start turning from a solid to a liquid just from the warmth of your hands!

In this experiment, Locke places Gally into boiling water, causing the weak bonds in the gallium to break apart, turning her into a puddle of liquid metal. But don’t worry—by using liquid nitrogen, we can cool Gally down and restore her solid form. Just like that, Gally is back!

🔬 What You'll Learn in This Experiment:
✔️ Why gallium melts at such a low temperature
✔️ How metal bonds break apart and reform
✔️ The surprising properties of liquid metal

Guess who’s back, back again, Gally’s back, tell a friend

Unfortunately, Gally doesn't get along with Aluminum. How rude

The glasses barely get up to eyeball height.

Is it classed as silver in colour or grey? Because it’s not silver it’s gallium. So wouldn’t it be gallium in colour instead of silver. 😅
