Thermochromic, fluorescent fluid I'm a total layman in chemistry and am working on an interactive sculpture project and therefore am researching into fluids that have certain properties - long story short:
we are thinking on having a transparent sculpture where a fluid is flowing through it, a fluid that reacts visually on the heat of peoples hands on their touch - so if people touch the sculpture, the fluid changes colour or even emits light in a fluorescent way.
Sorry, I am conscious this may sound super vague and really naive - I'm just trying to reach out to check out possibilities and may come up with interesting insights.
Is there any known way of achieving such an effect? Where could I continue looking after? Any help or pointer towards a certain direction is highly appreciated. Thanks!
While thermochromicity already was known for me, for example as thermometer for fish tanks like here, a search based on "thermochromic fluorescent fluid" as keyword yielded this video.

Beside safety, yet indeed, it is easier to fill the sculptures with a liquid / a solution of a fluorescent dye excited by black light from the inner of the (glass) sculpture and to wrap the container with thermochromic dyes. These are even commercialized as here and here.  "Black light" is an other name for ultraviolett light, and there are even hand-size battery powered lamps found in the chemistry lab, or in civil life to check banknotes.

Disclaimer: I have no relationships to the said corporation.

Addendum:  Examples of fluorescence triggered solely by the gentle warmth of a hand are not known to me (yet).
