a charge builds on your kite when its flying, this comes from friction with the air. air surrounding lightning storms is heavily charged* and you collect lots of electrons on the canopy. if one or more of your lines are wet or conducting in some way every time you break your connection with the ground you will be charged up. touching the water or ground once charged up will give you a jolt like touching a van der graph.
