K'nex Ice Cream Delivery Rollercoaster - "The i-scream coaster"

I created a workplace roller coaster that delivered packet ice-creams from the 1s't floor (where the freezer was) down to the ground floor (where a lunchtime fundraiser was taking place.) 

5000+ pieces, 100 hrs build time, 28m of track, top speed of 70km/h!

 

After the event, and filming, I added an extra section to the bottom part fo the track. The coaster stayed for a few months. Visitors were fascinated by it.

 

As we stared demolition, I made the bottom into a ramp for a couple of stunt videos of the train flying off the end like a ski jump.... :) 

 

 

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!!

 

 

"LOOPER 20-20" - a 20-loop K'nex 'launch' roller coaster.

Possibly a world record for the most consecutive loops in a K'nex 'launch' roller coaster. (the launch is at the end.....haha :)
20 loops, built in 2020 

• 20 consecutive loops
• 6300 pieces
• 17m gravity run-up
• 30m total land distance
• 48m track distance
  

 

Upside down K'nex roller coaster model

Yes, you would die on this coaster in real life.... It has a forwards and backwards loop, both from the upside down position, and two corners to fling you out of the coaster.

I built this quickly after the Goofy's Sky School copy - while I had the scaffolding up. 

Goofy's Sky School K'nex roller coaster

 Loosely based on Disney California Adventure's Goofy's Sky School / (previously Mulholland Madness).

I built the frame first and then lift hill, then removed scaffolding as needed.
