Youtube user Hknssn built a paper airplane-making machine using legos. As a last step, it launches the airplanes — a compressor shoots them about 2-3 meters off-camera — but you might have to watch the launch more than once. It happens fast!

Jason Allemann, who created these Lego mazes last year, built this beautiful and elegant Lego ball clock. The video shows how the rail system works with one ball being hauled up the chain every minute, then tipping the balance once enough balls have accumulated.

This LEGO machine, or LEGO Great Ball Contraption, is 17 different modules of incredible. Transporting 500 mini soccer and basketballs over 101.7 feet (31 meters), this hypnotic project was created in two years from over 600 hours of build-time by Japanese LEGO machine mastermind Akiyuky (of previous LEGO machine fame).

This video! Every new piece of machinery was surprisingly surprising. And thanks to Gizmodo’s Jesus Diaz for making a list of the modules, in order: 

1. Ball factory
2. Zigzag stair
3. Zigzag lift
4. Pneumatic
5. Cup
6. Screw T1
7. Basket shooter
8. Mechanical train
9. Screw T2
10. Screw T3
11. Spiral lift T2
12. Elevator & coaster
13. Fork
14. Spiral lift T1 & step
15. Catch & release
16. Belt conveyor & pinball
17. 5-axis robot S750

Thanks, @kvetchup.

Francisco Prieto animates the assembly of a Lego Millennium Falcon, Lego set 10179 from Star Wars Ultimate collector series. He writes: “Created using 3ds max and V-ray. A very long work over 3 years, modeling all the pieces by myself. and rendered frame by frame.”

And of course, because it’s the internet, there are (many) other versions of the Millennium Falcon’s assembly out there…

Episode 5 of James May’s Toy Stories is a great one: they build a lego house. The really interesting part is that they have to figure out how to make it structurally sound. They’re dealing with the physics of legos on an entirely new scale. 

After watching this, I’m guessing any kid will look at their legos a bit differently, no? 

The entire episode is online in 1, 2, 3, 4, 5 parts, but I’ve cued up a spot mid-show here (part 3 at 3m13s) for diving into the action, which may work well for 3 year olds like mine.
