The top 75 projects out of the original 200 were on display Friday at Northwest Junior High School's annual science fair.
"We have a couple of very good experiments on architecture. What types of structures support the most weight? What type of wing will fly the best? That's a good one. We have a lot of good projects, a wide variety," said coordinator Terry Cumberland.
Other experiments include long-time favorites, such as testing toothpastes and carpet cleaners for effectiveness. Some projects delved into the physics of the atmosphere.
The top three projects will go on to the regional science fair at Mississippi State University.
