When trying Balducci levitation for the first time ask a friend to assist you. You won't impress him for sure, but once you learn Balducci levitation, everyone else will be amazed! Ask a friend what is the best angle and distance. Once you calibrate this on your own body, you will know exactly what position to take when performing Balducci levitation in public, no matter what the configuration of space is. The only important thing is that the spectators are all in one place; if only one of them is separated at different angle, your trick will be unveiled.
