Can Play-Dough Conduct Electricity?
Play-Doh is a moldable compound made of mostly flour and salt. Play-Doh is a childhood toy used to learn at home and at school, and was even used to clean wallpapers. My goal for my genius hour project was to see if Play-Doh can conduct electricity. After weeks of researching, I learned that it can, and I am going to tell you why.
Vocab
Circuit-
A circular path that moves electricity
Conductors-
Something electricity can easily pass through
Insulators-
Something that electricity has a hard time moving through
High Resistance-
Doesn't allow electricity to pass through easily
Low Resistance-
Allows electricity to pass through easily
What is Play-Doh?
What it made of?
As said before Play-Doh contains mostly flour and salt, but it also contains tap water. Tap water is a big part of the recipe because it lowers the resistance. So, if the Play-Doh has a lower resistance, it will allow electricity to pass much more easily.
Circuits
Now that we know Play-Doh is a conductor, we need to learn more about circuits and how electricity can pass though them.

Circuits are made of 3 main parts. A power supply, a conductor, and an electrical device When I made my squishy circuit, I discovered I had to make a parallel circuit for it to work.
Why Parallel?
A parallel circuit worked best for my play dough circuit because electricity likes to take the shorter path. So if the Play-Doh is touching it will not pass through the electrical device, instead it will just pass through the dough.
Conclusion
The reason electricity can pass through the Play-Doh is because of the tap water in it. The tap water reduces the resistance in the dough which makes it easier for the electricity to pass through.
