In a nutshell, yes. The question is what the composition of the liquids would need to be and what the light would need to be in order to achieve this.

It's both! What I mean is that the temperature difference must be large enough to be perceived by the human hand. It cannot be a minute difference measurable only by a thermometer. :)

Hi hi, Sorry if this is awful and boring. Basically what I want to work out is a way to differentiate two different liquids by touch (specifically, temperature) after shining a light on them. A thermometer cannot be used. The variables open here are the compositions of the liquid (I'm going...

Hm, thanks. That doesn't seem to be quite what I'm after as it appears to be for "existing" stuff. And what I'm trying to do isn't sci-fi per se, it's just making sure I'm not making mistakes in real science written down. But that is potentially far too boring and simple for this forum.

Hi guys, I'm Rodwen. I'm a writer and scienthusiast looking for a helpful community to run with my bizarre scenarios and provide some feedback to stop me derping up the science in my books too much. I completed physics, chemistry, maths and biology in my final year of high school and also ran...
