Erik Maldonado of Mad Science of the Mid-Hudson, based in Goshen, visited the Butterfield Library in Cold Spring on Aug. 1 to lead a workshop.
In one demonstration, he asked a student to hold a model of Earth (below) ; the relative diameter of the sun, he explained, would be the width of the room.
In another exercise, students represented the solar system: those bunched in the center (below) were Mercury, Venus, Earth and Mars, the boy in the blue shirt is Jupiter and the boy in the red shirt is Saturn. The next closet planet, Uranus, would not be in the room.
In another demo (below), Maldonado balanced tennis balls on volunteers’ heads to illustrate that an object at rest will stay at rest.
