Does anyone know of an original science fair project?

My 14 year old son has wanted to become a scientist since before I can remember. An opportunity has come up for him to enter into a science fair but I need some ideas.

It would be the first science fair he has entered into so it doesn't matter if he wins or not, just the participation I believe would be a good experience for him.

There is no better place to ask than the TED community, all ideas would really be appreciated.

    I always liked testing chemical reactions. So as a kid if i could design a product that went boom for science that made me happy.
    Also you could perhaps try Kevin idea with various ways of filtering the water. Boiling and recondensing water can remove some of the salts, as well as perhaps testing a commercial filter, and perhaps another method.

      • Mar 11 2012: The video was speed up so your feeling was justified. If you search for lego in space their are a couple articles on who did it.
