Subject: I need input on practical experiements using holography.

I am enterning grade 10 and I am an amateur holographer who wants to 
use this median in Science Fair.  However, I must come up with a 
practical experiemts I can do with the emulsion recording, 
interferometry etc. THERE IS NO OTHER HELPFUL INFO. FOR THIS TYPE OF 
PROJECT AVAILIBLE ON THE NET.  I do not have the expertise to take a 
blind stab and need some ideas help me get started on what areas I 
might want to consider.  If anyone has any ideas I could elaborate on 
it would be most appreciative.    THANKS!
