The inventions were made by third-and-fourth grade students.

Miles Krog, 9, a third-grader got tired of having his Nintendo Switch end up on the floor. So he invented a lay down table.

“I lay my Switch on it and my snacks,” Krog said.

He used wood, screws and spray paint to make the table.

Olivia Clausen, 10, a fourth-grader at Community Christian School, gave her presentation for the invention convention virtually on Thursday. She invented the Olivia Launcher, a catapult to use for dog toys. "My dog loves it," she said.

“I can raise and lower it,” he said. “I carry it with me everywhere I play.”

His favorite games are Donkey Kong, Fortnite and Mario Kart.

Krog said his grandpa helped him with the research portion of the project.

“It took me four or five days to make,” Krog said.

Lane Peed, 9, a fourth-grader, invented a D.F.D. (dog food dispenser).

Jace Bockoven, 9, a third-grader at Community Christian School, demonstrates The G-1 Filtration System Thursday during the school's invention convention. Bockoven invented the system to get dirty water clean. It goes through two filters before emptying into a bucket.

“My mom was having trouble feeding my dog, so I invented this,” Peed said.

Peed said his dispenser stores, measures and dispenses the food. It was made by drilling holes in a PVC pipe and building valves and windows.

“Sometimes it jams,” he said.

Stylz Grall, 10, a fourth-grader, experienced a similar problem as Peed. So he created the Food-O-Matic.

The problem: “Getting up to feed the dog.”

Jersey Grall, 8, a third-grader at Community Christian School, shows off her Mobile Food Tray, an invention she came up with to combat crumbs. She said the product has been popular among her brother's friends.

“You fill the top hopper with food so later on all you have to do is push down on the lever or teach your pet to push down the lever,” Stylz Grall said.

Andrew Heath, 9, a third-grader, invented an ice cream holder to be used in cars.

“My dad couldn’t eat ice cream very easily,” Heath said. “My invention holds the ice cream in the car so you can drive safely and still have ice cream and not have a mess.”

The holder is attached to a large clip and rubber tube.

“It has an adjustable arm,” Heath said.

Lane Peed, 9, a fourth-grader at Community Christian School, operates his D.F.D, a dog food dispenser, Thursday during the school's invention convention.

Jace Bockoven, 9, created the G-1 Filtration system.

The dirty water goes through the downspout and travels through the first filter. That filer has rocks, sand, pebbles, more sand and charcoal.

The water then travels through the second filter, a bandana, before emptying into a bucket.

Olivia Clausen, 10, a fourth-grader, gave her presentation virtually. She invented the Olivia Launcher, a catapult used for dog toys.

“My dog got bored,” Clausen said. “This launches her toys for her. She loves it.”

Miles Krog, 9, a third-grader, explains his invention, the lay down table, during the school's invention convention on Thursday. Krog said he invented the table because his Nintendo Switch always ended up on the floor at home. Now he said he puts his Switch and his favorite snacks on the lay down table.

Clausen used wood, a big plastic spoon, stickers, paint and a dog toy.

Jersey Grall, 8, a third-grader, was determined to solve a problem — crumbs.

She got tired of crumbs hitting the floor, so Grall created the Mobile Food Tray.

The tray has straps and a cup.

The product has been popular at her house.

“My brother’s friends have already been using it,” Jersey Grall said.
