STEVENSVILLE — Students from four local high schools were challenged Friday to figure out better ways to use common home appliances during the 2019 Whirlpool Youth Innovation Challenge.

But the appliances they are working with are top secret, with students required to sign confidentiality forms to participate. That’s because they will be working on a project Whirlpool is actually developing to come out next year, said Ellen Dutton, product marketing manager of KitchenAid small appliances, a brand of Whirlpool Corp. in Benton Harbor.
