Static Electricity problem

[KBs PensNmore]

I know this isn't the right forum for this, but it's the only place I know where the knowledgeable people hang out. I'll put this in the electronics section also. I've been asked to make a Christmas display, that has a glass bowl mounted on top of a fan with polystyrene balls, 6mm dia, that blow trough a hole above the fan, there is fly wire above the fan. My problem is, that static electricity make all the balls bunch up on top preventing them coming into the airflow and stopping excess air escaping. Does anyone have any ideas on preventing this from occurring.
Thanks in advance,
Kryn
