I need a picture of liquid helium itself for my project on superconductors. I've looked all over but I can't find anything

[enigma]

I couldn't find any on Google in the first few pages.

AFAIK, it just looks like water (only you'd freeze to death instantly if you drank it).

You may do a search for "Bubble Chamber"

Bubble chamber sub-atomic particle tests were done in liquid helium. The picture will be a lot prettier than a pool of something that looks like smoking water.
