How long do legos last

Based on the differences in mass between the underwater and unweathered Lego bricks, the study authors project that the toys could last anywhere from to 1, years in the marine environment. Most Legos are made from a petroleum-based plastic known as acrylonitrile-butadiene-styrene ABS , and their presence in seas reflects a much larger environmental crisis. Microplastics can also accumulate in the food chain, potentially making their way into our bodies —though the health effects of microplastic consumption among humans is not clear.

While the Lego pieces examined in the new study appeared to be fairly robust, they did show signs of wear and tear. Earlier this month, Lego announced that it would be transitioning from ABS to a sugarcane-based polyethylene, as part of a commitment to making percent of its bricks sustainable by the year That servo presses down onto the mating piece which is sitting inside that yellow band. When the post on the lower servo is moved toward one arm of the puller it grips the lower LEGO piece tightly so that the upper servo can pull the two apart.

My fingers and hands are incredibly sore just from reading about this experiment. Sometimes my hands cramp from just an hour or two of hard pay with my bricks. Maybe I need to do more planning before crunching these little suckers together Someone's advice on this forum to avoid lotion and hand crime when working with bricks and raw, sore fingers is great advice as well.

Very neat, although I have to wonder whether constant assembly and disassembly might put more stress on a brick than occasional assembly and disassembly. Perhaps if the machine were run at a lower speed it'd take more cycles for the bricks to lose clutch power.

LEGO bricks last for centuries if discarded into the ocean, contaminating the environment for generations upon generations of sea life. According to the researchers and based on the study of LEGO bricks that have already spent years in the ocean before ending up on beaches, the toys could last up to 1, years before fully breaking down. Everyone loves LEGO building blocks — unless you accidentally step on one in the middle of the night, of course — but they are a total nightmare when it comes to pollution.

Because of this, they often end up in the ocean. Once there, they can endure for a very, very long time. Andrew Turner, lead author of the study, said in a statement.
