You're going to want to build this LEGO paper aeroplane folder

Wonderful things happen if you give a giant box of LEGO to a bunch of bored engineers. 

Pointless things, but wonderful all the same.

Built to promote the aerospace division of Arrow Electronics, this build uses several thousand pieces of LEGO - including some of those fancy pneumatic kits your parents would never buy you as a kid - forming an assembly line that can fold a single piece of A4 paper into plane, before launching it. 

Check out the final build above, and an explanation of the build below.

Unfortunately Arrow Electronics don't offer any step-by-step instructions for building your own version - so you'll just have to stick to traditional hand-folding methods for now.
