But... aren't all chemical reactions either endothermic or exothermic?

(as an A-level chemistry student, I can assure you that the answer to that one is yes).
The obvious choice would be something involving fire tbh. If it doesn't have to be particularly useful, just some kinda "the candle burns through the string and the flour falls on your sister's head" type thing would probably work.
Basically any thing involving a chemical reaction of any sort will do, and then google whether it's exothermic or endothermic.
Good luck :shades:

New comes from known ... Meaning, in order to come up with something novel, you need to run some rxns that are already known... find, run and study the known rxns for changes you can make to achieve a novel outcome... that is, what's the next step to something new? Good luck on your effort.
