It's 50 percent bismuth, 25 percent lead, 10 percent cadmium. That is one hell of an unhealthy concoction.

Zinc will also flash turn back to a solid. I worked at a Zinc platting factory. The zinc would harden before the splatter even hit you from the molten kennel

I just love how Nile has an easy bake oven in his lab

@rpelzer

I believe it was a Columbo episode where a man was stabbed on a private jet wirh a knife made of wood's metal.  Before they landed, the knife was dropped into a thermos of hot coffee to turn the murder weapon into a fishing sinker.
Update:  see below replies, it was actually an episode of Ellery Queen, not Columbo

@abs0lute-zer061

Quick search says it's Bismuth, Lead, tin, and cadmium. Yuck, but cool.

@Arcane_Eye

Learned about this metal in brief courtesy of Mistborn - Wood's Metal is an alloy involving cadmium to some relatively small percentage and is very not good to ingest. Another name for it? Bendalloy.

@TheItalianoAssassino

I love the random easy bake oven in the background ๐Ÿ˜‚

@Trident_Gaming03

A chemist being confused is both funny and scary

@ErulianADRaghath

Get some Field's metal next, unlike Wood's metal, it contains neither lead nor cadmium, making it much safer to handle.

I love this "Reggie's random mail for Nigel" series๐Ÿ˜Š๐Ÿ˜‚

@notkarma2984

Wood metal or Rose alloy, used for desoldering fragile components with large footprints(lots of legs). You add it on top of existing solder and mix together lowering overall melting point and adding thermal mass so solder stays molten longer, allowing to take off chips without needing heating fan.

Had a decent lump of woods metal as a kid. Was fun to play with it. Of course had no idea of itโ€™s toxicity.

@scoutdogfsr

We use this in firearm chamber casting. Works well if the caliber is unknown or if you want the evaluate the chamber dimensions of a given arm.

@five-toedslothbear4051

Formerly and sometimes I guess still used in fire sprinkler heads. The idea of being that once the heat rises enough the metal melts, and opens the water source. these days, I think sprinkler heads use mostly glass bulbs filled with liquid.

@michaelm7299

it has a very high thermal conductivity as well as low melting point. As soon as it contacts a cooler environment it dissipates its heat

@HyperactiveNeuron

Otherwise known as a Lippowitz metal. I used to work with one called Cerrobend. It liquified around 70ยฐC and I made molds of it in Styrofoam to shape gamma and electron beans for radiation therapy. It is composed of lead, tin, bismuth and cadmium.

@corneliusmcmuffin3256

Metals are great conductors so it makes sense it melts and solidifies really quickly

@AsekiBekovy

I like Field's alloy much more, expensive but lower melting point and not terribly toxic ๐Ÿ˜‚
