Robots, computers and solar-powered cars were on display for the kids.

"We're looking for our young people who are coming through the walls of the Texas Science and Engineering Festival to be those guys who are innovators and visionaries to bring about the next wave of what is hot," Gregory Harrington with Dell said.

Nine-year-old Aidan Arnett is fascinated by cars. He’s currently building a remote control car as a project with the Boy Scouts.

"We get to build our own motor and I'm going to make the transmitter and all that,” Aidan said.

James McElhanon helped students at Stony Point High School build their own car powered entirely by the sun. The solar car cost about $17,000 to construct and the students will be taking it across the country.

"These kids will be driving this car right besides highways and other stuff so we have to be really cautious,” McElhanon said.

This was the second year for the annual science festival.
