More than 35 high school students spent a part of June on the University of Utah’s College of Engineering campus to learn about exciting engineering concepts at this year’s Exploring Engineering summer camp.

Students from Utah, Idaho, California and as far away as North Carolina spent three days participating in demonstrations including building working hovercrafts that operate with just vacuum cleaners and guiding remote-controlled robotic balls.
