Question: what materials did you discover?

I worked to make new types of plastic that will degrade i.e. break down and won’t hang around for thousands of years. Plastic pollution is a big problem just because unlike other things it lasts a long time.

I also make materials that change colour if they encounter specific bugs (bacteria or fungi). This could be really helpful for doctors if they put it on the swabs they use to check if you are okay, as it helps them decide what medicine will help you out more easily.
