I hope this hasn't already been asked, though Im sure it has. I want to make a special hurricane for my bro and his wife for their anniversary. They were married on the beach. Im thinking some sand and shells, etc. Has anyone tired to use sand. It seems like it probably won't work, but I thought I would ask. If it's impossible, I don't even want to waste my time or wax. Im thinking the wax would probably crack around the sand.
