Water rides — Something that really attracts you!

The water rides are the most popular rides.　　 1.__ The boat slides down very fast into the water! You can buy your ticket before you go to the theme park. Then you do not have to stand in a long line. 　 2. _ If more than 10 people go to the theme park together, it costs less. There is a ticket machine beside each ride. You can stand in line for your turn. Or you can take a ticket that gives a time you can go on that ride. Then you can do something else while you are waiting.

3.__ This is because when you are scared, your knuckles become white!
