Best Answer

When we resperate, we release carbon dioxide. Plants take that in to make oxygen. BTB can not do anything with the carbon dioxide. Only if you add a plant in the container with the BTB, you can make it it's blue color again. A fun experiment is to add soda, like coke, to BTB and see if it changes.
