Scientific Clock Construction. Create your own scientific clock and watch science come to life. Using simple kitchen materials such as saltwater, aluminum foil, and pencils, electrical energy can be generated to power a digital clock.

Learn how batteries work and discover the magic of chemistry through a unique STEM experiment that combines knowledge and play. The set nurtures curiosity and shows that science can be simple, creative, and fun.

• How It Works: A typical battery has three main parts: anode, cathode, and electrolyte. When connected to a device, a chemical reaction occurs that produces electrical current.
• In the homemade battery, aluminum foil acts as the anode and the pencil graphite as the cathode. By mixing saltwater as the electrolyte, the LCD clock is powered by electrons.
