There are numerous success stories of teen businesses that were created in college dorm rooms and other modest circumstances. Below are some of the most recognisable names in the industry:

1. Facebook: Mark Zuckerberg and his friends started Facebook when he was a 19-year-old Harvard undergraduate. 
2. Dell: When Michael Dell was an undergraduate student at Texas University in 1984, he started upgrading computers for profit. He starting working full-time on his business when he was 19. Eventually, his company became the Dell Computer Corporation and then Dell Inc. 
3. Subway: Fred DeLuca opened the first Subway restaurant when he was 17. In 1965, Mr DeLuca needed extra money for college, so he decided to open his own business. Peter Buck, a family friend, lent him $1,000 and together, they opened Pete’s Super Submarines. A few years later, the company was rebranded and called Subway. 
4. Mashable: In 2005, Pete Cashmore created Mashable in Scotland when he was a teenager. The site was then a technology blog. Over the next few decades, Mr Cashmore has turned Mashable into a global media company.
5. Oculus VR: Palmer Luckey founded Oculus VR in June 2012, when he was 19. In August that year, Oculus launched its Kickstarter campaign and raised more than $1 million in three days. Facebook bought Oculus for $2 billion two years later.

Graphene is extracted from graphite and is made up of pure carbon.

It is 200 times more resistant than steel and five times lighter than aluminum.

It conducts electricity better than any other material at room temperature.

It is thought that graphene could boost the useful life of batteries by 10 per cent.

Graphene can also detect cancer cells in the early stages of the disease.

The material was first discovered when Andre Geim and Konstantin Novoselov were 'playing' with graphite at the University of Manchester in 2004.
