"I'm glad that you like the things I have, and I understand. Even as a resident here, people are not really friendly sometimes, which is not very good for a normally outgoing person like me. Even I have faced the horror of some people trying to eat me. But, enough about that, let's see more of my inventions, shall we?" Blue asked. Then, the elf walked up to a large steel device with a small compartment in the front. In the compartment is a spout and a button. "I present to you the water purifier! Have you ever faced the problem of a world with dirty water? Well not any more. This wonderful machine cleans the water by filtering it and heating it to boiling temperatures to kill all the germs inside it. Then, when it's ready and cool, you simply pull out a cup and press this button." Blue said happily. Then, he grabbed a cup off a nearby table and placed it in the compartment, then he pressed the button. For the time he held the button down, clear water poured from the spout into the cup. Then the flow of water stopped as Blue let go of the button to grab the cup. "Care for a drink?" Blue asked with a smile as he held the cup out for Rose to grab.
