Wouldn’t it be cool if kids could be inventors? They can! The Wouldn’t It Be Cool If . . . competition challenged kids ages 10 to 15 to share their invention ideas. Kids sent in more than 1,100 ideas, and four inventions were chosen as finalists. Competitors were asked how their idea used science, technology, engineering and math (STEM). The finalists got to pitch their ideas to artist will.i.am and other judges. Watch the video to see who made it through. The winner will be announced on April 25.
