Andrea Johnson/MDN -- Riley Held, who will be starting school at Erik Ramstad Middle School this fall, shows off her shovel-shaker invention. She will be entering her Marketplace for Kids invention in the first ever Bright Ideas Marketplace for Kids Showcase and Contest at the North Dakota State Fair.

Children from all over the state will have a chance to enter their brilliant inventions in the first-ever Bright Ideas Marketplace for Kids Showcase and Contest being held this year at the North Dakota State Fair, said Wendy Altendorf, the regional chair of Marketplace for Kids. Eleven-year-old Riley Held of Minot, who participated in the spring regional Marketplace for Kids event, is one of the kids who plans to enter the summer contest. Riley’s dad was mighty grateful for her “Shovel Shaker” invention this last winter when he was shoveling snow off the driveway. Riley invented a device that can be attached to a shovel’s handle that shakes rock salt out at the same time snow is being shoveled, saving the shovel’s operator from slipping on the pavement. She said her dad gave her the idea when the area was dealing with all the snow this winter. The summer event, planned for 9 a.m. to 1:30 p.m.
