I didn't take official classes for this one. I gathered information from wonderful sites such as this one and with perseverance and some southern ingenuity achieved success! Until today, I had no idea others had mutilated a blood pressure pump for this art...lol...i hid my "frankenstein" tool(named so because I cut it up and pieced foreign items to it to make a new creation). It isn't difficult really. Just need the right temp sugar, and enough wooooo saaaaah .
