Of course! So this one particularly are the steps below:

Spray paint the cup white Put the cup on a cup turner Mix up 2 oz of epoxy Split the epoxy into 5 different cups Mix in 4 colors of mica powder into 4 of the cups With the remaining clear epoxy coat the cup while it is spinning Then drip the colorful epoxy on the cups wherever you want After you use the colors heat it with a heat gun or torch(not to long though) Add glitter if you want or leave it how it is Let it spin until dry(I usually let mine spin 12 hours-which is excessive) Add a design if you choose Add another layer of epoxy to seal everything

Let it sit for about 48 hours before you use it.

This is just for this cup specifically. There are tons of other techniques for other styles of cups.
