As CBS 2's Dana Kozlov reports, the Ewert brothers have a rather advanced science project. But instead of a typical dry ice experiment, Chris and Andrew used batteries and a charger to make their hybrid Toyota Prius get 100 miles per gallon.


The information is not in context. There is no explanation of the statement "but instead of a typical dry ice experiment" then goes on to say they just added a battery and charger.

It is impossible to make sense of the statements without the connection between those sentences. Where does dry ice enter the equation?

There also is no data regarding the reason the cars as modified are illegal in Illinois.
