Creative Contraptions
When a popsicle stick snake launches into the air, it’s more than a surprise; it’s a lesson in stored energy and chain reactions. At the Playful Engineers Chain Reactions Family Program, participants build whimsical contraptions like Rube Goldberg Machines and domino towers to learn how force, momentum, and energy transfer work. This hands-on event supports curiosity, experimentation, and systems thinking through play. Each invention offers a chance to explore physics and engineering in action while observing how small changes ripple through an entire design. Participants can continue their experiments at home using everyday materials, turning curiosity into ongoing self-directed learning. – Registration is required.
Self-Directed Learning
Explore the science and creativity of chain reactions through hands-on engineering challenges at home. Whether building Rube Goldberg Machines or launching popsicle-stick snakes, discover how one small action can trigger a surprising series of events. These playful projects introduce concepts like force, energy transfer, and systems thinking, while encouraging experimentation, revision, and success through curiosity.
Domino Tricks
Dominoes offer a fun, visual way to explore chain reactions. Learn how spacing, patterns, and placement affect the outcome. Try designing your own layouts and test how each change influences speed and direction.
Cobra Weave Popsicle Sticks
This spring-loaded design stores energy in a woven line of popsicle sticks. When released, it bursts apart in a dramatic display. Learn about potential and kinetic energy by building and launching your own.
Rube Goldberg Machines
These complex contraptions use simple objects to complete a task through a long chain of reactions. Watch a few for inspiration, then sketch and build your own using toys, craft supplies, or household materials.
These activities support self-directed learning in physics, engineering, problem-solving, and collaboration. Chain reactions also show how changes in one part of a system can influence the whole. One small action can lead to many outcomes.
