== Natural Antimatter ==

Antimatter is naturally produced  by both (β⁺) decay and by high energy collisions between particles. Antimatter makes up a very small percentage of [[cosmic ray]]s, and is occasionally produced when those rays collide with the earth's atmosphere. Antimatter has also been spotted in the [[Van Allen belt]]s and forming above thunderstorms.

[[Potassium]] 40 will (very) occasionally undergo beta decay, producing an antielectron. As such, the average banana (rich in potassium) will produce a small particle of antimatter every 75 minutes.<ref>http://tertiarysource.net/ts.cgi/anti-banana</ref>
