Discover how a magnifying glass enlarges, how colors mix, how static electricity attracts, how sundials tell time, and how a motion picture works. Investigate air pressure, air flow, hovercraft, paper airplanes, and suction. Build a soap-driven boat, mix oil and water, experiment with evaporation, paint with sugar, and watch a balloon inflate itself.
