Volunteers holding cards representing astronomy (right), a physical science, and botany (left) - a life science, lend a hand to Dr. Science, who dons a detective jacket for this part of the show.
Dr. Science has the children focus on the spiral, and then after ten seconds, look at his nose. An optical illusion created by the spiral made it appear that his head was expanding.
Dr. Science, Doug Scheer, explains the four types of science - mathematical, physical, life and social.

"Dr. Science," Doug Scheer performed his act, "Wacky Science," at the Mary Johnston Memorial Library on Thursday. It included a basic chemistry experiment describing acids and bases, optical illusions, explaining the four types of science, states of matter and more. The act, which was part of the Iosco-Arenac District Library's Summer Reading Program included plenty of audience participation.
