Their Own Factory

Fun For A New Generation

How insights from Chuck's childhood form the foundations for more fun today.


Growing Up Fun

"When Dad came home early, we knew he had something new for us to try!" Chuck Knerr was raised on fun. His dad, Rich, along with his business partner Spud Melin often used their kids as testers of their latest inventions like Super Stuff. They knew which products would succeed by watching the childrens' faces.


Product Tester

Chuck's first product test didn't go according to plan but he had fun anyway and eventually got the hang of it!


Commercial Extra

Being in the commercials was big fun! Spud and Rich invited kids from the neighborhood to join in, making them more authentic. Spud even enlisted the help of their postal carrier!


Fun For The Next Generation

Chuck noted, "When I played with my daughters, I found myself doing all the things Dad did when he played with us. He always made everything fun!"


The Family Business Is Fun



During hot summer days, Chuck learned to sell by pulling his wagon door-to-door, selling water slides for $5.98.

With the charisma of a 6-year old and a snappy sense of personal fashion, he helped the neighborhood cool down.



Chuck remembers learning how important it was to demonstrate the visual fun of the product. That visual was found on the faces of children. Spud and Rich shot their own commercials in their front yards and filled them with kids from their neighborhoods. That's how they achieved such powerfully authentic images.



Spud and Rich were natural teachers. They trained Chuck to be curious and constantly look at things for how they might be better. "What if... " and "How about... " started countless debates over new ideas in constant brainstorming sessions.

Chuck's "Moon Gravity Machine" was inspired by the Apollo missions.  He used bicycle wheels, a backpack frame, buckets and barbell weights to represent 5/8 of his body weight to "feel" the moon's gravity.



Spud and Rich worked hard so they could have the freedom to play. They made work fun and play was even funner! When not at work, they would often be found hunting or fishing. Their sense of humor and fun-loving natures certainly rubbed off.

This photo was Chuck's idea but he quickly regretted it as the rope tightened around his ankles. "It was incredibly painful. The smile on my face is actually just gritted teeth!" Dad pulled on my arm to take some of the weight off and we got the shot.

Chuck Was Moved

"I was convicted I'd been wasting the gifts God had given me."
