Everyone has those mysteries of the universe that keeps them awake at night. While some of us are pondering life on other planets, one man is answering serious questions about long time durability of Lego bricks.Some of us are lucky enough to have been given Legos when we were kids, and somehow they have managed to survive into adulthood. Maybe they live in a box and your children will play with them one day, or maybe you’ve been adding to your collection since day one and have built something amazing in the process. We already know how much weight they can handle, but what about longterm use? You’ve probably never counted how many times you’ve used any of your bricks — even your favorite ones. Because of this, you’ll never know when one of those bricks will stop being useful. Phillipe Cantin decided to find out exactly how long the average lego brick could hold up, so next time you’ll know.Using an Arduino, a servo with a custom-made arm, and a pair of 3×2 bricks, Phillipe built a rig that would constantly connect and disconnect the two bricks until they would no longer connect together. The top and bottom connectors seemed to wear evenly, making it so the satisfying snap was completely gone when trying to connect the two bricks. While this test didn’t make it so the bricks couldn’t connect to other bricks, by the time this test was done the bricks would never join together again. Using his current rig, the bricks took 10 straight days of abuse before wearing down to the breaking point.It should surprise no one that Lego bricks can essentially survive a lifetime of abuse, since they do that already. Plenty of people have Legos from when they were kids, and there are daycare facilities and stores that have Legos out for kids to use all day, every day. Durability is one thing you can count on with most Lego bricks, as the most dangerous thing outside of wear and tear for a is one being accidentally stepped on or scattered across a highway during a move.
