Introduction: How to Make Electro Dough ( Conductive and Insulated )

Sophie, Minnie and Marnie will walk you through all the steps on the dough making and how to use it to learn about circuitry. *

- Conductive dough is made with a salt base, which allows electricity to pass through the dough.

- Insulating dough is made with a sugar base, which doesn't allow electricity to conduct through the dough.

Step 1: CONDUCTIVE DOUGH - Mix the Ingredients!

Add the water and salt to a pan. Bring to the boil until most of the salt has dissolved

Step 2: Coock the Dough!

Sieve the remaining ingredients and add them to the pan. Stir the mixture continuously over a medium head until a ball of dough forms.

Step 3: Get the Righ Texture!

Remove from heat and knead in a little flour until a desired consistency forms.

Step 4: INSULATING DOUGH - Mix the Ingredients

Mix together the sugar flour and oil. Rub the mixture in your fingers to form a crumb like consistency.

Step 5: Add Water.

Add the water in small amounts until you have a dough like consistency and it naturally forms a ball. (Not all the water maybe needed)

Step 6: Get the Right Texture!

After a dough ball can be formed, knead flour into the dough to remove stickiness.

Step 7: Test Your Insulated and Conductive Dough!!

Electricity is what causes lightening, it plays a role in making your heart beat and it's what turns your lights on. You've probably felt it in the small shocks that come from static electricity. In our circuits the dough acts as a resistor, limiting how much electricity can pass through. Try experimenting with different shapes and volumes of dough to see how it affects the circuit.
