How do LEGO® bricks work?

Have you ever wondered how LEGO® bricks stick together and not fall apart? If one of your parents or grandparents still have some of our very first bricks lying around, you’ll discover that they don’t have tubes on the inside and they might not stick together as well as newer pieces.

Godtfred Kirk Kristiansen, the son of our founder Ole Kirk Kristiansen, was the first one to discover that our little bricks have a much higher 'clutch power' when there are evenly spaced tubes on the inside of each brick. The tubes on the bottom interlock with the studs on top of other bricks. The studs get neatly wedged in between the tubes and the sides of every brick making them stick together firmly.

The clutch power of LEGO bricks has made it possible to create bigger and bigger sets without them falling apart. LEGO bricks are in essence a whole construction system with endless possibilities. The only limitation is your imagination!
