Sound can be minus decibels. The quietest place on Earth is Microsoft’s anechoic chamber in Redmond, WA, USA, at -20.6 decibels. These anechoic chambers are built out of heavy concrete and brick and are mounted on springs to stop vibrations from getting in through the floor.
100 Mind-Blowing Brick Facts
LEGO bricks withstand compression better than concrete. An ordinary plastic LEGO brick can support the weight of 375,000 other bricks before it fails. This, theoretically, would let you build a tower nearing 3.5km in height. Scaling this up to house-size bricks, however, would cost far too much.
Legos have a uniform system. A Lego brick made in 1960 will fit perfectly with a Lego brick made today.
The surface area of an average-sized brick is 79 cm squared.
