How to make a bottle rocket car?

How can i make a bottle rocket car? I have limited materials to use on the project. The materials i can use are:
- 5 straws
- 1 regular size water bottle
- 1 sheet of a paper towel roll
- 4 wheels
- baking soda
- vinegar
- hot glue (glue gun used to apply it)
I thought up of a couple of designs and they all failed. Can anyone help?
