HUMAN TRIAL. “A human sensory panel was employed to study the D2O taste. Triangle tests based on two samples of H2O and one sample of D2O (or vice versa), with random success rate of one-third, were presented to the panelists in a randomized order. Panelists were asked to pick the odd sample out—to smell only, to taste only (with a nose clips), or to taste with open nose.”
