Liquid Metal Embrittlement - Gallium vs. Aluminium
Bringing gallium and aluminium together has some interesting and occasionally rather explosive results, as Dan found out in this little tale from the prep room.

Liquid metal embrittlement is a phenomenon where ductile metals, like aluminium, become brittle, when exposed to certain liquid metals, like gallium. The mechanism by which this happens is not a chemical but a physical one, where the liquid nature of gallium allows it to get into spaces within the aluminium structure.
This embrittlement of metals is real a hazard in manufacturing industries as well as other fields where ductile metals may come into contact with liquid metals.
