This is our first model/failure of our concrete piece.
My group cut out waves into foam and put them around
inside of a cardboard box. We were going to test it out
by using plaster, but found out we didn't buy enough, so
decide to just go ahead and pour in concrete.
Carlos, Ellie, Christy, and myself poured the concrete.
We took turns, pouring the water and concrete mix, while one of
us stirred. We used wood shavings as our aggregate in this model.
