BRISTOL, Tenn. -

A local elementary school in Bristol, Tennessee had a very special guest speaker Wednesday.

One of the original Rocket Boys, Jimmy O'Dell Carroll, from the movie October Sky was at Haynesfield Elementary answering questions.

Students in pre-k through sixth grade at the school have been working on projects for a science expo, including projects on rockets.

Carroll says the Rocket Boys think it's very important to get out and speak to children. "We're excited about math and science, we're excited about them having an adventure, we're excited about them doing things in the future. And they are our future," Carroll says.

The science expo will be Thursday night at 6 p.m.
