>Now just put the BB into the end of the pen & full the string to fire.                                                                                                                                                                                                                                                                                       >Optionally you could use the party popper to cover the end to stop some of the pressure escaping. Do this by making the party popper wider at the top by using a knife, then thread the string through & tape up the end.
