She Rose to the Challenge! The Eureka! ePals-Smithsonian Challenge: Using up to 5 common household items, invent a new product that will make your daily life easier, more fun or more efficient. The competition was run through a collaborative website (ePals). Ailis Einarson's invention of an overnight pet feeder was a winner! Ailis is a 9-year-old grade 4 student at Castle Park Elementary. Inventions were explained via a one-minute video, a 3-slide PowerPoint or a document with a digital image. Check out Ailis' video: Click here.
