Today was the redesign day.  We used our redesigned mortar mixtures to build our redesigned walls.  Some of the groups used more water.  Most groups went with a clay, clay, and sand mixture.  One group went with a clay, clay, clay mixture.  Most of the groups went with a reinforced wall.  Last time we observed these held up better to the demolition ball.  Here are some pictures of our new walls.

"We added to more water but it was less soupy then last time." Laura
"When we built it the first time it was really runny but today we used the same amount of water and it was too dry."Emma
