Put about one cup of epsom salts into each bowl. Add ONE DROP of blue food coloring to one of the bowls and mix until evenly distributed. Add ONE DROP of green food coloring to another bowl and mix.

Put the white epsom salts onto a paper plate and gently shake back and forth to get an even layer. Place your hand inside the jar.

Use a paintbrush to coat the jar generously in Mod Podge. You want to use a generous amount, but not so much that it’s dripping off the jar. First paint around the bottom rim of the jar, then the body of the jar, then the top rim. (Notice that in the picture below there’s no Mod Podge on the rim. IGNORE that, just follow my instructions instead.)

Starting at the bottom rim of the jar, roll in the epsom salts. Next roll the body of the jar and the top rim.

Stand the jar up onto a separate paper plate and add some Mod Podge to the top lip of the jar. Sprinkle some epsom salts onto the lip.

Repeat this process for each color. Allow each jar to dry for a few hours. Use a clean paintbrush to loosen and remove any salt that fell inside the jars and to gently knock off any excess on the outside of the jars.

Spray with a clear gloss sealer. Let dry for about 20 minutes, repeat for a total of 3 coats.
