The Mission Eggcellence Challenge is a yearly competition to see who can design the best cars.
Months of scrutinizing building plans, product testing, and last minute corrections, all boils down to this one pivotal moment.
"I'm sure we are going to lose," said Cole Cheatham of Neshoba Central. "I just came because my teacher asked me if I wanted to."
Well, that and Cheatham is one of the several hundred talented and gifted students involved in the challenge.
"We hope we have some future engineers here," said Terry Gressett, a TAG teacher at Union.
Using physics principles and some trial and error, 80 different teams comprised of four members each, all built a car that could win a year's worth of bragging rights.
In order to qualify, the car needs to hold an egg and a ping-pong ball, roll down a slope, hit on impact without the egg breaking or the ball escaping the vehicle.
Win or lose, everyone seemed to have an eggcellent time.
The Mission Eggcellence Challenge began back in 2006, created by Mississippi State University.
Students in kindergarten through twelfth grade compete, in four different age divisions. Last year, more than 200 teams took part statewide.
