We've all seen it happen. Eighth grader(!) Charlie Sobcov wanted to help put a stop to the 500 million birds that are killed each year in North America from collisions with windows, so for his science fair project he unveiled a plastic decal that is invisible to human eyes but bright as a stop sign to birds. When placed in the middle of a window, it stops bird collisions immediately. What I want to know is why didn't someone invent this long ago? The only decals that existed before were black and obstructed the view from the window. So far testing has been limited to the Sobcovs' family cottage where the decal worked flawlessly. Sobcov has recruited 40 volunteers to test the product on their homes. If all goes well, he is considering marketing his new invention. This boy has got a bright future.
