Why do we need to wear a space suit in space?

Professor Gizmo (Amazing Science Presentations) gives expert video advice on: Why do we need to wear a space suit in space?; Why do things float around in space?; Why do stars twinkle? and more...

Well, you've heard of these guys going into space? Twenty million dollars for that suit - no, just kidding! But you do need a suit to go into space. If you're going to get outside of the space craft you do need a suit. There's no air; there's no atmosphere; there's no pressure on our body. Plus out in space, because there's no air, there's a regulation of temperatures right from the sun. One side of you would be extremely hot. The other side would be very very cold. So you need this special suit to protect your from pressure, from heat, and even particles that might be flying around in space. So you have to protect yourself. And if you didn't have the suit, you couldn't even breathe. There's no air.
