8ft K'nex Chinese New Year Music Wheel - Year of the Snake

Made in our office for Chinese New Year 2025 - The year of the snake. 8ft high, 5000+ pieces and powered by a desk fan. See also our 8ft Christmas/Lego Ferris wheel, and 8ft Australia Day Animation wheel

8ft K'nex Animation Wheel: 5000+ pieces, 48 frames

For Australia Day, my office desk buddy and I converted the fantastical 8ft motorized Christmas K'nex+Lego Ferris wheel, which before that was the 8ft "stone" that literally rolled across our office entry (a nod to the Easter story), into an Australia Day wind powered 8ft animation wheel.

The strobe light flickered on one frame at a time as it came past to reveal the animation without the scrolling blur.

The video couldn't capture that in real life for the frame rates did not sync with the strobe rates... 
But it real life, it mostly worked 0 but gave you a headache pretty quick!

K'nex Kafé Koaster: 4m high, 14m long, gazeebo roof-top Roller Coaster and Ferris Wheel

I was asked to create a K'nex roller coaster for a youth group's hot dog fundraising stand, and this is what I built them. It fascinated the children and adults alike... and they sold out.
Most common question: "How long did that take to create?" (About a month)
Children could ride the roller coaster for $5 - but had to be under 2cm tall to ride.

Highest point is over 4m high, 14m of track - it really made out stall amongst 30 others stand out!!

 

 

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 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.

K'nex Teddy Bear Ferris Wheel

After building the regular Ferris Wheel from instructions, and modifying for a school project (turning it into a wind powered wool winder) I thought my Daughter's teddies would like a ride. So we raised it and widened it. And in an effort to become a multi millionaire I put the fun book I wrote on it as a fitting product placement... (I'll settle for two sales: www.theparkqueues.com ).
