       This is not so much an idea, more a rueful reflection that even serious design competitions can fall for the idea that merely filling things with helium will magically make them float.   

       And in the meantime, keep an eye out for next year's Electrolux competition - clearly they are gullible!

       "he’d like the product to be inexpensive though helium refills would be costly, and he hasn’t finalized the material of the filter itself" So basically he has nothing at all. I don't see how this could begin to work. It isn't even clear if this freshens or filters air, as there is a difference.

       I like the compactness of that double myth. Methane is (1) odorless, and (2) not a large component of farts.
