CHESTERTOWN Raindrops on her eyeglasses led Summer LaPrairie to an invention and recognition. The North Warren fifth grader was one of two North Warren students who were in the top 100 inventors in the state in a recent competition. Sierra Liebelt thought up the idea of dispensing juice from her refrigerator without having to open the door. I got tired of pouring juice for my little sister, she said. The students are in Poul Carstensens class and they took part in the Invention Convention 2007, a state-wide competition sponsored by General Electric. The annual statewide invention education program has students from kindergarten through eighth grade identify problems and design and build inventions to solve them. The top 100 entries are chosen as semi-finalists based on creativity, originality, complexity, innovation, practicality, and impact and are displayed at the Schenectady Museum and Planetarium through June 9. Both Liebelt and LaPrairie were in that top 100. In her description that she submitted to the convention, Summer said it rains a lot where she lives and she was sick and tired of cleaning her glasses 24-7. She invented her Eyeglass Shield 3000, using sturdy plastic to cut a pair of visors to clip on her glasses and keep the rain off. They help prevent them from getting wet, dirty or scratched, she said. Liebelt said her invention her juice dispenser would allow liquids like juice or milk to be dispensed outside the refrigerator through a tube and faucet system. The top 100 semifinalists will go to the Schenectady Museum on June 7 for an awards ceremony and to announce the top three winners in the state. The initiative of the kids was amazing, Carstensen said. One student came up with the idea of diet gum, in a broccoli flavor. Inventive but probably not a hot seller.
