Clip Length : 00:04:38

This NBC Learn video, part of a series on "Chance Discoveries" in chemistry, tells how three different chemists in two countries over more than 30 years happened to make a white, waxy substance during lab experiments that, once recognized as potentially useful and developed, became polyethylene -- the most common plastic in the world.

Clip Length : 00:03:52

This NBC Learn video, part of a series on "Chance Discoveries" in chemistry, tells of the lab accident in 1903 that led to the development of the first safety glass -- just as the first automobiles were being produced. Safety glass revolutionized the manufacturing of car windshields, preventing countless injuries and fatalities in automobile accidents.

Chance Discoveries: Kevlar

Date : 11/03/2011

Clip Length : 

In this NBC Learn video, part of a series on "Chance Discoveries" in chemistry, veteran NBC News war correspondent Richard Engel tells the story of lab work done in 1965 by DuPont chemist Stephanie Kwolek that unexpectedly produced Kevlar, a lightweight fiber five times stronger than steel. Kevlar fibers can be spun into anti-ballistic, shrapnel-resistant material for protective body armor worn by police forces, military troops and those in combat zones, including Engel himself.

Chance Discoveries: Graphene

Date : 10/06/2011

Clip Length : 00:04:35

This NBC Learn video, part of a series on "Chance Discoveries" in chemistry, tells the story of two scientists who used their curiosity -- and Scotch tape -- to isolate single-layer sheets of graphite one atom thick: graphene, one of the thinnest, strongest materials known. The two won the 2010 Nobel Prize in Physics for their discovery.
