Step 2: Method
2. Once you have weighed the dry ingredients, put them in a plastic or crystal bowl and set aside.
3. Now measure your wet ingredients and mix them all in a plastic or glass bowl. They won't mix perfectly, don't worry about that. You should have a little less that 2 tablespoons total of wet ingredients. Maybe you won't need that entire amount. Depends on the weather that day. If it's raining you'll need less moisture. But more on that later.
4. Start adding the wet ingredients to the dry mix one teaspoon at a time. Don't add more than that amount at once because the mix will start reacting. Whisk the mix at the same time you're adding the liquid.
5. When you have added two teaspoons, test your mix by pinching a little bit in your hand. If it stays together and feels damp, your mix is ready. But if falls apart, keep adding liquid, 1/2 teaspoon at a time and testing the mix after each addition. The finished mix should feel like damp sand in your hands. It should not feel wet. If you think you have added too much liquid, add a little corn starch as needed.
6. Now lets get ready to mold. Fill the mold you chose with some of the mix. Add as much as you need so the powder is compressed in the mold, it should be tight. You can leave it in the mold or remove it. I decided to remove it and it kept its form. Some people find that it is almost impossible for it to keep its form after it is removed. So if you've never done this before, leave it in the mold until it's completely dry.
7. Let it dry for 24 hours.
