From Salt to Water Test Paper
Filter paper soaked in cobalt chloride solution and dried until blue becomes a water test paper. Clipped against a leaf, it turns pink where water vapour leaves the surface, which lets a class compare transpiration from the upper and lower sides. Gentle warming drives the water off again, so the blue colour returns and the paper can be used again.
Handling
Wear gloves, weigh the salt without raising dust, wash hands afterwards and keep the container closed so the contents stay dry.
