We haven't found too many practical uses for ferrofluid -a mix of oil and iron particles that appears to morph and change shape when exposed to magnets-aside from fun desktop toys. So now that we've discovered it becomes a nightmarish-looking blob creature when you mix in a little color, maybe it's time to just stop making this stuff?

I'm probably not going to sleep tonight after watching these unsettling ferrofluid experiments from YouTube's Chemical bouillon , but at the same time I'm also oddly soothed by the seething, bubbling display of colors. It's equal parts beautiful and unsettling, like a lava lamp that might be slowly giving birth to a monster.
