Making Mars Bricks

A scientists known as Ryan McGlothlin, shows that radiation can be blocked by combining a sugar like substance and another substance that looks like flour and then bakes the mixture into a brick like structure. Apparently the sugar like substance was polyethylene, and the flour like substance is topsoil. In addition, McGlothlin, a chemistry major at the College of William and Mary, and chemistry department chairman Richard Kiefer are planning on using this mixture to develop a way for astronauts to protect themselves from the radiation on Mars' surface.
