We know a lot about
bricks, especially how they interact with bare feet. A team of physicists at Lancaster University in the UK wanted to learn something new, so they chilled some Lego pieces to near absolute zero and discovered they have some intriguing thermal properties.
The scientists used a special "dilution refrigerator" that plunged the plastic to a mere 4 millidegrees above absolute zero. Absolute zero is theoretically the lowest temperature possible, which works out to –459.67 degrees Fahrenheit or –273.15 degrees Celsius.
The researchers popped four stacked bricks and an astronaut minifigure into the super-cool machine. You can check out the complicated process in a video deep-dive into the experiment.
The toys survived their journey to becoming the world's coldest Lego pieces ever. The team collected data from the experiment and discovered Lego-like plastic structures might be useful as a low-cost construction material for future dilution refrigerators.
