When I say this activity is easy, I totally mean it. There’s nothing hard about it but it sure does look like a lot of work. If you make this, be prepared to impress everyone with your skills. They’re going to think that you’re uber creative and that’s up to you to correct them or not!

Supplies needed to make DIY Bath Salts

  1. 1 ½ cups Epsom salts
  2. Red, orange, yellow, green, blue, and purple mica powder

I told you this was simple, right? Once you have the short list of supplies, it’s time to get started in making the bath salts!

To be certain that you get all the colors of the rainbow, divide the salts up into 6 bowls. Then you get to add in the coloring so that you can make them the right rainbow colors.

Make certain to get a glass jar or a small mason jar with a lid that you can store the salts in. You can then layer the rainbow colored salts and make a rainbow right there in the glass.

While it’s probably best to go in the order of the colors of the rainbow (ROYGBIV), it’s up to you if you want to. I think that no matter what, it’s going to look awesome when you get done.

Will colored bath salts change the color of my bath water?

Yes, they will. The good news is that it shouldn’t discolor your skin. The bath water will turn a fun and funky color but your skin should be just fine.

How do you use bath salts?

The easiest way to use bath salts is to fill up the tub with warm water and add in a few scoops. They’ll instantly dissolve with the warm water and the coloring of the bath salts will start to spread.

If you use more than one color of bath salts in the water, you’re going to end up with a bath that has a different color and will be of what they all mix to be. More than likely it will be a dark color of purple or something like that since the darker colors are going to be more powerful.
