So much so, he wanted to make it a part of him, literally. - [Narrator] Unfortunately, the Lego bricks weren't strong enough and it wasn't for another nine years 'til he would try again. - [Narrator] That model, the MK1, only took five days to build, of course, like any good inventor, he got straight to work on an upgrade.
