Go to the circle marked on the floor and take a closer look on the behavior of an experimenter. You got burned due to sulfuric acid liquid that was spattered on your hand. Turn back and go to the sink by moving along the marking on the floor. Stand in front of the sink and turn the tap on. Wash out both hands on which sulfuric acid liquid was spattered with the running water. You completed the mission. Let’s wrap up what we have learned with a quiz. Time out. Try it again.
