If you fancy having a play this weekend, you might like a go at creating some of your very own conductive play-doh.
Once made, it can then be used to create any number of different circuits with the ability to create any shape you can imagine from the moldable dough. Check out the video after the jump.
Squishy Circuits was developed at the University of St. Thomas by undergraduates Samuel Johnson and AnnMarie Thomas and basically uses a couple of special ‘Play-Doh’ recipes allowing the dough to serve as either a conductor or an insulator.
How Squishy Circuits Work
The concept behind Squishy Circuits is both simple and ingenious. By using two different types of dough—one conductive and one insulating—you can create a variety of electrical circuits. The conductive dough is made with ingredients like salt and water, which allow electricity to flow through it. On the other hand, the insulating dough contains sugar, which prevents the flow of electricity. This combination allows for the creation of complex circuits that can light up LEDs, power small motors, and even create sounds.
For example, you can create a simple circuit by connecting a battery pack to an LED using the conductive dough. By placing the insulating dough in between, you can control the flow of electricity and make the LED light up. This hands-on approach makes learning about circuits and electricity both fun and educational.
Applications and Benefits
Squishy Circuits are not just for fun; they have educational benefits as well. They are an excellent tool for teaching basic concepts of electrical engineering and physics to children and beginners. The tactile nature of the dough makes it easier for young learners to grasp abstract concepts. Moreover, the flexibility of the dough allows for endless creativity, enabling users to experiment with different circuit designs and components.
Teachers and educators have found Squishy Circuits to be a valuable resource in the classroom. They can be used to demonstrate series and parallel circuits, resistance, and even more complex topics like sensors and switches. Additionally, because the materials are inexpensive and easy to find, Squishy Circuits are accessible to a wide range of people, making STEM education more inclusive.
Beyond the classroom, hobbyists and makers have also embraced Squishy Circuits. They offer a low-risk way to prototype and test new ideas. For instance, you could create a simple alarm system or a basic robot using Squishy Circuits. The possibilities are only limited by your imagination.
More information and recipes for the dough are available from the Squishy Circuits website. The site offers detailed instructions on how to make both the conductive and insulating dough, as well as project ideas and troubleshooting tips. Whether you’re a teacher, a parent, or just someone who loves to tinker, Squishy Circuits provide a fun and educational way to explore the world of electronics.
