# How tall can a Lego tower get before the bottom brick is crushed?

Categories: Community, Science & Technology

Of all the bits of information available online, the exact number of Lego pieces that could be stacked, one on top of the other, before the bottom piece was crushed under the weight of the tower itself has remained elusive -- Until now.

A team of researchers from The Open University in England has finally come up with an answer to the popular query, which has been a subject of debate for years on websites like Quora and Reddit.

But it wasn't as simple as building a Lego tower.

According to BBC Radio statistics program More or Less, engineers used a hydraulic testing machine to calculate the strength of one standard square Lego brick.

They were able to exert more than 4,000 newtons (N) of force before the square gave out into a melted shape described by the BBC as "a small square of warm camembert."

The team determined that the average maximum force Lego bricks can stand is 4,240N - the equivlent of 432 kg.

So how many Lego bricks does that equal?

The grand total of bricks a single piece of Lego could support is 375,000.

A Lego tower with this many pieces would be approximately 3.5km high, significantly higher than Mount Olympus according to the scientists.
