Every year around the holidays my living room is taken over by a roller coaster or ferris wheel made of sticks and circles. Other times of the year small robots or vehicles or planes made of the same materials zoom around the kitchen. If there are no youngsters in your house you may not be familiar with K'Nex. They are the next generation's version of Lincoln Logs and Tinkertoys. Phillyburbs has a nice history of the company, located in the Philly area. If any readers have nieces or nephews they don't know what to get for birthdays or holidays, I strongly recommend any K'Nex product. I get a big kick out of telling family and friends where the company is based.
