Impossible Challenge?

I think I may have accepted an impossible challenge. I said I could learn to do a one-handed handstand, legs together like a pencil, held for 3 seconds.  Since acepting this challenge I still can't find a video of someone successfully completing this feat. Only people holding one-handed handstands with their legs wide apart to help balance. If anyone has any suggestion for how I can actually, within the limits of physics on the planet earth, balance, straight body, on one-hand for 3 seconds, please let me know.  So far I only have these videos of super-human Shaolin monks balancing on their fingertips for inspiration:
