Insulating Dough

This dough serves the opposite function of the one made in my last Instructable-- rather than trying to help the flow of electricity, we're doing everything we can to stop it :)

This is done through a few different ways:

For one, this recipe uses a lot of sugar, which is especially important because it doesn't contain salt or other electrolytes, so there are no free ions available to carry an electric charge.

We also use distilled water, which is already purified from the dissolved salts and minerals that other waters may have. Because of this, there aren't any free ions available to conduct electricity.


This dough is also super useful if you're trying to make a dough circuit, as it can be placed between conductors to prevent short circuits.

See how to use this dough in a project here, along with our conductive dough!

Supplies

  1. 1/3 cup distilled water
  2. In place, you can substitute some regular water and increase the oil content, although this may decrease the resistance of the dough slightly
  3. 1 cup flour
  4. 2 tablespoons oil (vegetable)
  5. 1/2 cup sugar

Combining Ingredients

Add all of the ingredients into a bowl. Mix until it forms into a dough

Storing

Depending on the consistency, add more distilled water or flour.

If you wish to store it, wrap it and place it in the fridge. Ensuring it is properly covered, it can last for several weeks.
