ST. CLAIR SHORES, Mich., Oct. 3 (UPI) -- A Detroit-area class of sixth graders has learned from first-drop experience how to prevent an egg from breaking when it's dropped 30 feet.
The 27 students of Avalon Elementary School in St. Clair Shores, Mich., were given two weeks by science teacher Paul Rossi to devise a protective system to prevent eggs from breaking, the Detroit News said.
The students' objective was to build a container that would cushion the impact of being dropped from the top of 20-foot bleachers.
One disposable plastic food container filled with facial tissue and cotton batting didn't do the job, while another cardboard box containing crumpled plastic shopping bags and Styrofoam packing chips attached to a parachute preserved the egg.
Rossi told the students the egg's outcome didn't affect their grade much.
"Whether or not the egg survives is only worth 10 points, so if the egg breaks, students can still get a B on the project," he said, adding only about half of the eggs broke.
