As soon as I was old enough not to swallow it! My big brother had lots! I think I started following the instructions when I was about five.
What was your most challenging K'NEX creation?
The most challenging project was "Bones". I used anatomy books to get realistic ideas of how a skeleton should look. I also had to do alot of work with the motors for the hand and the programming for the eyes.
Do you have a favorite past K'NEXpert, if so who?
I like looking at all the projects by past experts!
