When I was a kid, I loved Legos. So I was, of course, pleased when my kids started playing with them. In the last year or so, my kids have outgrown them. And while having all the Legos put away makes it a little safer to walk barefoot across the family room, it does make me a litte sad. Which is why, I guess, I have a soft spot for stories about Legos.
Like, for example, a BBC story asking just how many Legos can you stack on top of each other (How tall can a Lego tower get?, Dec 3). Turns out, you can make a pretty tall tower.
Ian Johnston and the team do two more tests to be sure we hadn’t just happened upon the strongest Lego brick in existence. And in fact they were impressed at the consistency of Lego manufacture.
The average maximum force the bricks can stand is 4,240N. That’s equivalent to a mass of 432kg (950lbs). If you divide that by the mass of a single brick, which is 1.152g, then you get the grand total of bricks a single piece of Lego could support: 375,000.
So, 375,000 bricks towering 3.5km (2.17 miles) high is what it would take to break a Lego brick.
Here’s a graphic to help visualize 375,000 Lego bricks.
