  • Step 2

    Microwave the bowl and mixture for one minute. Give it a quick stir and then, microwave it for another minute. The mixture should now be slightly thickened.Continue microwaving the mixture in 20 second intervals, stirring between each interval. When the mixture starts to look like mashed potatoes, take it out of the microwave and cover it with a wet paper towel to let it cool down.Tip: Be careful when handling the bowl as it will be hot! Alternative option: If you would like, you can also cook the mixture on the stove until it has thickened.

  • Step 3

    Once the dough is cool to the touch, knead it a bit until it has a well-mixed, smooth consistency. If the dough is too dry, knead in a little water. If the dough is too wet, try sprinkling in a bit of baking soda (not too much though!).Once the dough is ready, follow along below to create some cool sea formations!

    For faster results, your creations can be baked in the oven at 175 F for 45 minutes, but the heat will turn your creations light brown.
