Probably one of the most neglected household items (but most useful) are adhesives.According to Wikipedia, an adhesive is, basically, a material that adheres (literally) two materials together. Their origins are prehistoric in origin as the first adhesives used (natural gums and other plant saps) were estimated to exist at least 6000 years ago. Aside from gums, animal glues that were created from materials such as buffalo hooves.
Now, thanks to modern technology, we do not have to gather saps from various plants or from animal hooves for our adhering activities. There are "super glues", for one, named such because of their very strong sticking properties. I was a victim of this type of glue when a bottle accidentally dropped on my shirt, pouring all its contents, while I was doing some project. Up to now, the dried glue has not come off yet.
Adhesives are used in many ways that we wouldn't have probably noticed. Glues are used in making scrapbooks, handicrafts, clothing (oh no), furnitures, woodworks, and houses (cement, in essence, is a glue that keeps our houses from falling apart. Manufacturers also put adhesives behind hooks so that they can stick to our walls without the need to drill holes. Or, we can use glue to make super gigantic high school-ish geeky projects.
The most important use of adhesives today, I guess, is in sticky notes!!! The adhesive used in these pieces of paper are somewhat special because they are not strong enough to stick stuff together (durably) but they are strong enough to stick in places where we want them stuck--to remind us of our commitments. What is life without sticky notes in this amnesiac world? Well, your guess is as good as mine.
Whether you like it or not (and I know you like them staying because of their uses that you have taken advantage of countless times in your life), glues are here to stay.
