Welcome to KnexKrazy.com - a casual collection of my adventures with K'nex. Perhaps it will spark an idea of what you can make!

K'nex Underwater Turbine Test

Just testing how a 'windmill' would spin underwater over some vertical jets in the floor of the pool.

K'nex Self Swing

I wondered if a rotating weight would be enough to make a swing swing all by its self, just like humans can. Not bad. Will try a 'proper' attempt some day.

"Nudge" K'nex ball roller

 A little ball contraption built in a few minutes while waiting for lunch.

K'nex Perpetual Spinner

With a little less friction, and breaking the laws of physics, this knex contraption would actually spin forever without the motor running...
Ok, so there was no intention to make this into a perpetual motion looking machine. This was a quick build while some friends with kids were over.
