Thanks to everyone! really helpful!

just the person who drinks it.

I need to understand what's actually doable.. I would go crazy with designs if i could, but I still need to present them in a realistic way. The substances will react and create a certain colour, can this be displayed on different shapes or does it need to be a stripe?

There are already commercialised tests that detects the most frequent ones, i guess we would use the same substances.. as a Designer what Im interested about is the design and the colour of them

Hi everyone, I am developing a project to raise awareness about drink spiking. I was thinking what if we could create sone sort of straws that turns on another colour when the drink is being spiked? Currently is completely hypothetical, but I would like to understand if concretely is possible. If so, would be best to have the straws with lines (which would change colour) or any design could be applied?(like stars, or typography). As well which colour would be actually doable? thank you for your help Sara
