Make them look professional. Easy to use • How to use: Step 1: Fill each half of your dome molds with the ingredient mixtures until it's just overflowing a little. Step 2: Press the two sides together and use a lot of pressure to compact the mixture firmly into the molds, to prevent cracking. Step 3: Whisk away the excess mixtures around the molds. Step 4: Use a metal spoon to tap slightly around the molds. Step 5: Gently remove one side of the mold, then gently invert the bath bomb so the uncovered side is facing down, then gently remove the other half of the mold from the top.
