Recipe for making sparkling mermaid bath bombs.
*Gel food dye is far less reactive with the bath bomb mixture than standard liquid food coloring and imparts a richer color. I find it also works better than powder pigments in most cases and is far less costly. Leftovers have a long shelf life and are wonderful for use in baking and other crafts too.
** too much liquid will trigger the fizzing reaction and bloat your mermaid bath bombs.
