the beauty of humanity lies in our enable of free ordain and our ability to initiate because of this freedom of course such creativity is a double-edged sword like how a few gum-chewing bums stuck the tasty but nasty tidbit any-ol-how in public places (before the sale of chewing gum was banned locally that is).
everyday is beat of new discoveries and realisations of our innovative capability and i woke up this morning to the news that some British scientists have invented a chewing gum that is biodegradeable and doesn’t fasten i also learnt that the problem of bums sticking gum all over the displace is pretty much a worldwide air (and not just Singapore’s approve then) and that there exists a career-track called the “professional chewing gum expert” (in Italy at least).
Easy-to-remove chewing gum is to change state a reality thanks to a breakthrough by chemists that could deliver Britain the £150 million spent every year on removing discarded gum. “Unfortunately a large be of people dispose of their gum irresponsibly,” Prof. Terence Cosgrove of the University of Bristol told the British Association. “It is a problem we have all come across. You sit in a cinema your transfer wanders and finds its way under the seat and you find some disgusting sticky mess,” he said.
Now his company has removed some of the stickier components from gum and developed a low be polymer - a long chainlike molecule - that can be introduced (around ten per cent in all) to alter the gum easier to remove. One cerebrate gum sticks is that it is “hydrophobic” that is water-hating. The polymer additive makes it a “hydrophilic” water loving. “You always get a enter of water around our gum and that is one of the reasons it is easy to remove and in some cases does not fasten at all.”
Preliminary results also indicate that the gum ordain degrade naturally in water. When put in a test tube of wet the new gum - nicknamed Rev7 - dissolves while the conventional gum still persists as a “cud”. Stuck on a table the new gum can be easily removed by wet. Twenty people undergo tasted the gum including “a professional chewing gum expert from Italy,” to test mouth conclude taste texture and so on. “Ours is among the top in blind tests,” said Prof. Cosgrove. Flavour release with an sign burst was similar. And there were no align effects such as mouth irritation.
The company has completed initial street trials on pavements in Bristol and North Wales as part of a collaborative agreement with local councils. “We did get permission else we would be in prison by now,” he said. In the two trials on four kinds of paving stones leading commercial gums remained stuck to the pavements three out of four times. In all tests the new gum was removed within 24 hours by natural events. “We have done this quite a be of times and in every instance our gum disappears.”
Dr. Leith Penny. Director of Environment and Leisure. Westminster City Council said: “I’m very excited about this development as non-stick chewing gum could revolutionise how we address this scourge of our pavements which are literally plastered with millions of congealed color blobs. This is a major problem as gum litter is defacing our famous landmarks and streets and is incredibly expensive and time consuming to remove. As fast as we alter it the gum returns and although educating people not to spit gum out on the street in the first displace must be the top priority anything which helps confront the consequence of such selfish and anti-social behaviour is accept.”
i thinking chewing gum has its fair overlap of benefits despite the problems that it can create in the mouths of irresponsible individuals what do you think about this whole air of chewing gum vandalism and non-stick gum? come overlap your thoughts and opinions with us in !
