TULSA, Oklahoma -- A lot of unusual problems were solved Friday at an engineering challenge for middle and high school students.
They built boats out of aluminum foil and loaded them down with pennies, worked on a better paper airplane and built all sorts of contraptions for the 23rd annual Tulsa Engineering Challenge.
It's an event that attracted 1,000 students, mostly from outside Tulsa. They competed in events designed to keep them interested in science.
"We want them to know about math, science, engineering and technology jobs. They're very lucrative, they pay very well," Chriss Chavez, with the Tulsa Engineering Foundation, said. "Most kids know what it takes to be a doctor or a lawyer. They don't know what it takes to be a scientist or an engineer."
The event is for students in 4th through 12th grades.
