Over 80 Year 10 students competed in the Noosa District State High School CO2 race day.
The students worked for a term and a half designing and manufacturing tiny streamline rockets.
The day culminated in some students' cars competing in the state titles held in September at the Maryborough Technology Challenge.
Two students competed in the general shop category against over 90 students from 25 schools across the state.
NDSHS students Riley Crawford and Aaron Towle placed 10th and 16th respectively.
Industrial technology teacher Mick Endicott was pleased with his students' results.
"This was a good result with their times only a fraction away from competing in the national final," Mr Endicott said.
NDSHS student Jack Bell finished a very creditable sixth in the state challenge, which was good enough to send his car to the national final.
"(Jack's) car did even better at the nationals finishing third overall. A great result for Jack and it will give us inspiration to put more cars in this category next year," Mr Endicott said.
Mr Endicott sent his car away to compete in the teachers' division and was pleased to finish second at the state titles and overwhelmed to win the national final.
"This is another great result for our school as we have shown in these competitions how creative and innovative our industrial department has become," Mr Endicott said.
