How can you give people statik shocks using a trampoline?

ummmm od question but i know the answer lol....you rub your feet against the bottom of the trampoline < with socks on> and maybe jump around a little then put your fingure close enough to someone< like a 1/2 inch> and that should do the trick.... doesnt work every time tho FBALL50 thanks for answering this question i have been looking for this quiet a long time now commander2000
