Personal Concrete experiment

These pictures are process pictures of the mold i made of concrete to experiment. I first cut out a piece of blue foam insulation and then i carefully cut out the waves on the top that the desert group decided to use to resemble the waves in the sand. then i put the foam in the bottom of my card board box. I mixed the concrete and then poured it into the box and left it sitting over night. Then i ripped the box away from the concrete and cut out the foam from the bottom. Then i ended up with a nice non- cracked concrete mold.
