How to Make the Waterfall:
1. Get some aluminum foil and make a mold of what you want one side of the waterfall to look like. Be sure to spray it with something that will keep the resin from sticking to the aluminum foil. I found that "Pam" cooking spray works just fine.
2. After mixing in the catalyst, pour in some Polyester Casting Resin to your desired thickness, which in mine was about a quarter inch deep.
3. Once that's dried, take out your resin waterfall and wrinkle up some more aluminum foil, spray on the "Pam" and then wrap it around the resin waterfall that you've arleady created, with the aluminum foil side down, leaving just enough room for you to pour in the second batch of resin. Pour, let it dry, then remove your waterfall and voila! All done
