How to make lavender bath bombs with natural ingredients, including essential oil and lavender buds. The recipe makes six to seven medium-sized bath bombs suitable for adults and most children.
Sprinkle the decorative dried lavender buds into the bottom of each cavity of the silicone mold. Less is more.
Place all the ingredients except the witch hazel and the second lot of lavender buds in a bowl. Use your fingertips to mix them thoroughly, break up any lumps, and fully incorporate the oils into the dry ingredients. I highly recommend wearing nitrile or latex gloves for this since the mixture can be drying on your skin.
Spray a few mists of witch hazel and continue mixing with your hand. Add a few more sprays and mix. Keep repeating until you can squeeze a handful of the mixture, and it holds its form. You do not want the mix to be sopping wet, so spray just a little at a time.
Pack the bath bomb mixture into each cavity of the mold. Press down firmly, and leave to harden overnight.
Push the now-hardened bath bombs out of each cavity. You can use them right away, but they will last for at least six months if stored in an air-tight container.
