6．
The bank of England is making plans to introduce plastic banknotes to the UK．
Paper notes，meaning pieces of paper money，have been used in England for more than 300 years，but replacing them with plastic ones could be better．
Plastic notes were first introduced to Australia back in 1988．Since then other countries，including Romania，Vietnam，Mexico and Malaysia，have also begun using money made in this way．
Fans of water sports，such as surfing，find this type of money more useful and easier，as they can take it with them in the water and won't worry that it will fall apart．It is also good for people who by mistake put clothes in the washing machine with a note in the pocket!
It is more hygienic （clean and free of bacteria） than paper money as it absorbs less bacteria（the simplest and smallest form of plants，some of which cause disease）．And it is stronger．This means it lasts longer．According to a survey，a usual 5 note in the UK lasts around six months，while the $5 Australian bill lasts for an average of 40 months．
A downside of plastic cash is that it costs more money to produce．Cash and money-counting machines will also have to be adapted to accept the new money．
It is expected that the Bank of England，who hopes to start printing plastic notes from 2015，will introduce the money slowly，using the most common notes first．
