"Commentators have criticized Emoto for insufficient experimental controls and for not sharing enough details of his approach with the scientific community.[9][17] In addition, Emoto has been criticized for designing his experiments in ways that leave them prone to manipulation or human error influencing the findings.[9][18] Biochemist and Director of Microscopy at University College Cork William Reville wrote, "It is very unlikely that there is any reality behind Emoto's claims."[9] Reville noted the lack of scientific publication and pointed out that anyone who could demonstrate such a phenomenon would become immediately famous and probably wealthy.[9]"
