This scientist performed an experiment where he weighed a pot with soil and then grew a seedling in it for five years. During this time, he only added water to the plant. At the end of five years, he weighed the soil, and it weighed the same as it did at the beginning of his experiment. He concluded that the water he added to the tree was what gave it more mass.
