John wanted to show Mary the new experiment he was doing. They went to his laboratory. There, he was feeding some rats putting a little of the waste products in their foods and drink. In a first sight, things were alright. Any rats were dead and only a few were ill. But they were going to have babies and that was the surprised. Those babies were born in a wrong way, without eyes or legs. John trusted that the company would make some machines to solve the waste products problems but Mary wasn't as sure as him.
