Giselle, the daughter of Dr. and Mrs. Andrew Bazos of Bridgewater, invented The Retainer Container and submitted her idea to the Region 12 Invention Convention. The wristband safely stores retainers while children eat and, at the same time, makes it “cool to wear.” “You have no idea how many students’ retainers I have had to dig for in the trash,” said Burnham Principal Cathy Colella, Giselle first won at the local level and went on to win at the regional competition held at Western Connecticut State University. The University of Connecticut hosted the statewide convention, and it was there that Giselle earned a top place as a 2017 state finalist.
