Firefighters with Central Yavapai Fire Department obeyed the third- and fourth-graders at Mountain View Elementary School this past week as the students chanted "Drop it! Drop it!" Plastic cups, cereal boxes, toilet paper tubes - all with a raw egg stuffed inside - rained from above as the firefighters tossed each package from their ladder truck.
The students are all in a Wednesday afterschool engineering class where they learned about protective materials that could keep a raw egg "alive" after falling from a certain distance.
CYFD Captain John Fedema and firefighters Ron Litchfield and Marc Mazzella started tossing the packaged eggs from the ladder hoisted 26 feet in the air. Each of the 26 parcels fell onto the blacktop where teachers opened the sometimes oozing, dripping boxes and bags to check for viability.
The surviving seven eggs next plummeted to earth from 60 feet, and the two that "lived" through that experience dropped from 90 feet in the air.
Fourth-graders Brandy Gutierrez's and Graciela Arredondo's egg-in-a-shoebox remained intact to win the experiment.
Others weren't as well protected, like Angelica Nevarez's egg. She used cotton balls, paper, a box, more paper, rubber bands, more paper, and a bag. But, alas, it failed at 60 feet.
So did third-grader Brandon Hughbanks' egg, which he said he packaged with cotton, lots of grocery bags and tape.
The class is one of the STEAM - Science, Technology, Engineering, Art and Math - courses that Mountain View offers.
