The Guinness World Records world record for the largest human DNA helix involved 4,000 participants, achieved by the Medical University of Varna (Bulgaria), in Varna, Bulgaria, on 23 April 2016.
Guinness World Records also recognized the world record for the largest model of DNA; it measures 43.5 m (142 ft 8.4 in) long and was created by Ryerson University – Faculty of Science (Canada) in Toronto, Ontario, Canada, on 7 May 2016.
The experiment works by smashing a banana and mixing it with salt, water, detergent, and rubbing alcohol so the strings of the DNA become solid and visible, CBC News reports.
The event was organized by Laurentian University biology professor Thomas Merritt, as part of a national science outreach event called Science Odyssey.
“We do this DNA thing every now and then … with smaller groups of kids, but I’ve never done it with more than 20 or 30 kids,” Merritt said. “We had 10 times that many kids, and it was fantastic.”
