A few years ago, we made a bath bomb that was stress-free: they were ubereasy to make and helped to calm your anxiety after a long, crazy day. But they weren’t exactly the cutest to look at. So we perfected the recipe and decided to give it another go! Bath bombs are fairly easy to make. All you need is an acid, a base, and a binding agent, so you can make a no-frills bath bomb using only citric acid, baking soda, and water. But give this recipe a go for a therapeutic bath that leaves your skin silky soft.
