So tell me more about scuba diving!
Well scuba diving is a blast first off.  Scuba divers bring their own equipment so they can breath underwater.  The advantage of course is getting to explore more of our oceans!
When did it start?

Yes, it has advanced quite a bit with different breathing machines available.  They even have machines that will use your own gases recycled!
That's amazing! Are there any other fun facts you want to share?
A lot of people can't scuba dive because they can't handle the mental side of it and that is why it is important to get certified and make sure you can do it before just heading out to the ocean.  It scared me a little bit at first.

They used special effects to make the Yowie Yahoo and climbing equipment to fly around. When asked about the missing performers, they said they sent them away on free Great Barrier Reef Scuba diving tours. Then the Hex Girls
