Mix 4 Tbsp. of Mod Podge (you can also use white school glue), 2 Tbsp of water, and food coloring. (Only a few drops, add a little at a time until you get your desired color) Pour mixture into jar. Turn jar so the mixture will coat the entire inside of the jar.* Pour mixture out. Wipe off any excess from the rim of the jar. Place jar upside down on wax paper covered baking sheet. Bake at 200° for 30-40 mins.
*Mixture will be opaque at first. It will clear after it bakes.
