Lindemann, along with his student stage crew, tested different gravity car prototypes over the summer. After picking a model to roll with, the group created a 10-step instruction manual for creating the cars. On Wednesday, groups of four to five students were tasked with creating their own vehicles.
Until the day of the project, details of the exercise were kept a guarded secret from the 10th-graders.
"The only thing they knew coming in there this morning was this was about gravity," said Principal Lee Thomsen.
The day began with a science lesson on gravity. After the project was revealed, the students had exactly four hours and 15 minutes to design and build cars before practice runs began.
One group decided to throw the instruction manual to the wayside.
Instead of creating a car with a high back to sit up against like all the other teams, they created a car with no back so they could lay on their stomachs.
That decision turned out to be a good one, said 15-year-old Jess Sterrett. In the upright cars the center of gravity isn't strong and it feels like you're on two wheels, she said. Their design was more stable and the steering wasn't out of control.
"When we're laying down you don't go anywhere, you don't feel like you're gonna tip over," Sterrett said.
Other groups weren't so lucky.
"It's scary, you don't have any brakes on these things so it's very hard to control when you're going at a very fast rate," said Josh Cole, 15, who crashed not once, but twice in his gravity car, resulting in scraped knees and a cut ankle.
Cole's favorite part of the day was his first ride the time he didn't crash down the sidewalk bordering 800 South at Rowland Hall.
"Even though everybody crashed it was fun and we had a good time. Nobody got seriously injured. Nobody broke an arm," he said.
