Play all audios:
The singing toothbrush and the snack sax will debut Friday at Balboa Boulevard Magnet School’s “Invention Convention.” At the convention, 31 third-graders who have been developing inventions
since September will exhibit their prototypes, explain the problem each invention solves, and attempt to sell their products to parents and teachers with a commercial. A winning entry will
be selected and sent to the national “Invent America!” contest sponsored by the United States Patent Office. Among the contenders are a toothbrush that plays children’s songs to encourage
youngsters to brush their teeth and a saxophone equipped with a dinner plate attachment for those long, hunger-inducing gigs. The national contest--open to students in kindergarten through
eighth grade--began in 1987 after officials in the Patent Office noticed that domestic applications for patents were waning. The winner in each grade category takes home a $1,000 savings
bond, and interviews with late-night television guru David Letterman are not uncommon. Balboa students have competed in the contest for the last five years, said third-grade teacher Christy
Wyatt. The Balboa students have definitely taken to the project, Wyatt said. “They’ve become little inventors,” she said. “You give them all sorts of problem-solving situations . . . and
they’ve learned that when they grow up and get a job they will have to be creative and inventive in that job.” She added: “We have a lot of little Thomas Edisons, believe me.” MORE TO READ
