public domainLightweight sports equipment, like tennis racquets and golf clubs, are often made from graphite. Theodore Graygraphite lubricant Graphite is prized for both its strength and weakness.

public domainThe forces that loosely hold graphite together are named after Johannes Diderik van der Waals.

On an atomic level, graphite has a sheet-like structure where carbon atoms lie in sheets that are only weakly bonded to the overlying and underlying carbon sheets.

Geckos can climb vertical surfaces for the same reason graphite sheets stick together: van der Waals forces.public domainpublic domain
