Mondo Knows Facts
Natural wine corks can compress up to half their original width
Trapped cellular air pockets allow natural cork to compress tightly inside bottles
Natural cork comes from the thick bark of the cork oak tree, Quercus suber, harvested without killing the tree. Its unique cellular structure contains microscopic pockets of trapped air, allowing cork to be compressed to under half its volume. When inserted into a wine bottle neck, it expands outwards to form an airtight seal.

- Is this really a everyday life fact?
- Yes. It sits on the Everyday Life shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
