Fun Fact

Crushing weight: A single standard Lego brick can support a weight of about 4,240 Newtons, equivalent to roughly 950 pounds, before collapsing.

Glossary

compressive strength (noun)
The resistance of a material to breaking under compression. In 2012, Open University researchers calculated that a single Lego brick can support 375,000 others.
