Toy Car Rocket Fun

For our Honors Physics class we were required to test out how fast Hot Wheels cars would go (a.k.a. the speed or velocity) when strapped to a C-class rocket.  The process went smoothly, but the actual experiment went a little different than expected...

**NOTE** In this Instructable, there are two different tests.  The steps for the second test will be under the first steps so if you read both it may be a bit repetitive.  The first test did not work, so I would advise using the second. But even then it didn't work, this is just a requirement for our class.
