Does anyone know where I can get kg of metal that is liquid @ room tempature? I have never got a chance to play with any. Whats the most safe?

we used to play with mercury when we were little kids. what the F is up with that?
"ooh, it's so heavy!" "wow, neat!"
am i gonna die young?

:thumbsup: for less toxic. no idea why we had it, but it was in the medicine cabinet when i was a kid. is there any reason people used to have it in the old days?Originally posted by: ggnl
I'm pretty sure metallic mercury (the kind in thermometers at least) is non-toxic.
Edit: NM, I guess it's still toxic, just less toxic than other forms.

You played with it? Like in your hand? Without gloves?

heh. i still vividly remember my high school chemistry teacher removing a hunk of phosphorous from whatever liquid contained it in the jar. that day i learned that phosphorous and oxygen have a good time together.Originally posted by: BW86

my dad told me that he used to play with mercury too, in chem class. The teacher would pass it around the room and let everyone hold it![]()

top it off with the fact that he was a dead ringer for Beaker from the Muppets... man, what a classic moment. he was alright btw.
A lot of thermometers today use alcohol-based solutions as well.Originally posted by: Mark R
Yeah, you can get less toxic liquid metal alloys. They're used in thermometers.
If you buy a thermometer today, it won't have mercury in - it'll have a special metal alloy called galinstan [a mixture of gallium, indium and tin (latin: stannum)]. You should be able to get it from a decent chemical supplier - however it's quite expensive (about $2-3/g I think).
Mercury was a common substance in schools, and attitudes to safety were considerably different in the past. It was common practice to store bar magnets in a bowl of mercury, so they floated on the surface (you just picked one off when you wanted to use it), and it was perfectly acceptable to allow pupils to dip their hands in it, etc.
