YouTube description:

A metal alloy spoon melts in tea.

Featuring Professor Sir Martyn Poliakoff and Senior Technician Neil Barnes.

Why not use Gallium?
Well - besides the fact it's not what we were sent by our fan - Gallium has a very low melting point. It'll melt in your hand... Not as fun as a spoon that is normal in the hand but then melts in hot water!

All I can think is Wood's Metal.
But I'd think he's know that.

Wood's metal, also known as Lipowitz's alloy or by the commercial names Cerrobend, Bendalloy, Pewtalloy and MCP 158, is a eutectic, fusible alloy with a melting point of approximately 70 °C (158 °F). It is a eutectic alloy of 50% bismuth, 26.7% lead, 13.3% tin, and 10% cadmium by weight.

Hey! This person on the Interwebs sent us this thing. We have no idea what's in it. Let's melt it and fart around with it!

They did spectroscopy on it (3:50)

Field's metal.
