How do you spell R-E-L-I-E-F?

Caleb's Science Project is due tomorrow... and just a few minutes ago, about 10:40 pm, he completed it!!!! What a relief.... He's feeling pretty good about it. He made a passive solar desalinator... and I guess we discovered why passive solar is NOT the technology used in the real world for this... we had pretty poor output... 1/2 tsp in a day!!! But it's proof of concept anyway.

Here's the proud science student with his display.... We love ya buddy!
