so easy. takes about 5 minutes and uses things you have around the house. best part.
here it is:
so in order to get this, all you'll need is an old jar, bottle or some sort of container that will achieve a good seal. i had a mason jar around, so used that.
then you'll need, some water, some food coloring of your choice, and some sort of oil.
see how easy? fill jar with some water, color it, and then top with oil. voila!
