DO a systematic exploration of spark gap spacing against spark length.

Or, compare a multiple gap against a single one.

Compare blowing air across or through the gap against no air blowing, or 
different air speeds.

All of these don't require building anything new, just using what you've 
got already built.

Depending on the "rigor" of your science fair, a winning project is not 
just sizzle, but one that demonstrates systematic and repeatable 
measurements.  For instance, have you standardized your measurement of 
"spark length" for longest streamer? Do you run it multiple times and 
measure each time?
