Students at Pennsbury High School in Fairless Hills have broken their second Guinness World Record in four years by creating the longest-ever synthetic double helix structure, writes Dino Ciliberti for The Patch.

The structure was built last May on the grounds of Pennsbury High School. It measured 624 feet (190.350 meters) in length. That completely obliterated the previous record of 246 feet.

Witnesses from surveying company Gilmore & Associates helped measure and validate the completed structure.

The idea to build a record-breaking DNA structure grew out of National DNA Day. Biology teachers at the school had each tenth-grade student construct their own piece of DNA and decide which chemical sequence they wanted for it.

On May 25, the students and teachers connected all of the segments to create the longest synthetic double helix structure ever.

“Our ultimate inspiration for breaking this record was our students,” said Biology teacher Amanda Pettit.

Pennsbury High School previously found itself in the Guinness Book of World Records in 2019 when Pennsbury High School Senior Prom shattered the record for the most lipstick kiss prints on a mural (41,692).
