I don’t know if inogen oxygen concentrator can be found underwater but I’ve heard of the thing once. I’m going to ask the science teachers if they knew something about it. Let me guess. Uh, used in aquariums? So fishes can breathe normally? Used by some scuba divers? To get oxygen while doing things underwater? Well, enough of that. BRB, consulting Mr. Google!

We are in the 21st century now and things are getting more high-tech each day. No wonder there are already Online Schools which benefit most people from coming to a real school where they will learn about things. I prefer that kind of school, if you’d ask me. It benefits both parties- students and teachers. No more messy classroom, no need to wake up early to go to school, no more visual aids for the teachers. It’s just online all over. Cool, isn’t it?
