An engineering student has managed to build a functioning pinball machine using only K'Nex.

K’Nex has been around for less than 30 years but has already become the building toy of choice for elaborate creations that are impossible to build with Lego. Tyler Bower just demonstrated the ...

Here’s a slightly bigger K’nex ball machine that doesn’t seem to move as much, but also isn’t a full freaking pinball machine complete with meta game. Thanks for the tip, [Itay]!

When you see this working Skeeball machine made out of nothing but K’nex and a few rubber bands, you’ll be both awe-stricken and ashamed of your own projects.

Given enough pieces of K'NEX, the construction toy system designed and produced by a Montgomery County company, one can build all sorts of things. But what about a fully-functioning pinball machine?

This is Clockwork, my fifth major K’nex ball machine, and my largest and most complex K’nex structure to date. It took 8 months to build, has over 40,000 pieces, over 450 feet of track, 21 different ...

The result is the “World’s Largest K’NEX Ball Machine,” a towering kinetic sculpture 23 1/2 feet tall that fills the open stairwell of the museum with plastic balls looping on tracks ...

This machine made out of K'NEX beats all of the human-flippers out there attempting the viral challenge.

The machine was built over the last year by Austin Granger. It's the second-largest one ever made on record. Granger also made the record-holding one in 2016.
