DIY Rainbow Jar Tutorial for Mason Jar Crafting

A bit back, I ran an article about How to make a Nebula Jar. I loved it, the kids loved it, and judging by the amount of people that have written me complete this project, you all loved it as well. Personally, crafts that have to do with space or earth or elements, really make me happy. There are so many COOL THINGS in nature and I love to incorporate them in my blog.

This project brings all of that together again: Rainbow Jars.

I thought…why stop at Nebulas? Or Galaxies? Or Elements? RAINBOWS, DUDE, RAINBOWS. Plus, with all the rainbow food I have on MD, its time to bring some rainbow crafts, you know?

Enough with the small talk, let’s get our craft on~!

Clean glass jar with a lid
Tempura paint (rainbow colors)
Cotton balls
Water

1. Fill the first layer of the jar with water
2. Add several drops of paint to the water till you get the color saturation you are looking for, put the lid on and shake to mix the paint and water (or you can stir)
3. Stretch cotton balls and add them to the water until the bottom is filled with cotton, pressing them down into the water with a stick or butter knife. The cotton balls act as a buffer to keep your color into place.

IMPORTANT: The tip here is to use a lot of paint and a lot of cotton. You need to make sure there is enough cotton to soak up most of the water in each layer, otherwise, they will bleed together and turn brown eventually. That would not be a rainbow.

Now keep repeating the steps to build your layers-
