They had a portable party ballon helium tank. They opened up the end of a syringe and put the helium in. They put the plunger back on and put on a 31 gauge tip at the end of the syringe and injected it into the softball before a game. They said "this sucka will fly!"
Does this really work??? Helium injected softballs???
