Subject: Is it possible to make artificial gills for humans that don't have to be...

surgically implanted.  (Sorry, wasn't enough room in the other box for my 
question so I had to finish it here.)  Even though I am a 7th grade 
student I would like info that is above that level, I can handle stuff at 
the Teach/Prof level and I have resources that I can use to help with 
anything I don't understand, but I need the most detailed info I can get.  
I am doing this for a Science Fair project and I am running out of time.  
I am finding it harder and harder to find anything on even just fish 
gills.  Even if you can just give me locations to look at I would be 
happy.  I just need to get my hands on any info I can find.  I know how 
gills work and all (not in detail, but the basic stuff) so I am not asking 
you to put any info about that.  I'll be happy with even the slightest 
amount of info that I can get, thanks.
