Every now and then , someone on the net discovers a " secret " feature of an everyday utensil – such astoasters – and mind , as they say , are blow out .
Now , a viral position depart around the Internet express a use for the ridges you see at the bottom of salt shakers . accord to the stake , the ridges are there to be scraped to better the current of salt .

People were , of course of instruction , vaunt off by the hack for pouring a honestly alarming amount of table salt onto your intellectual nourishment without having to go through the effort of shake . Others , however , were skeptical that this was the intended purpose of the rooftree , rather than a neat side effect .
In all likelihood , the trick is n’t what the ridges were plan for , specially as plenty of other glass bottles and jounce have these ridge along the bottom , and not much will take place when you scrape the bottom of a Coke bottleful with a spoon .
One plausible explanation post to Quora by someone lay claim to be a commercial-grade glass contractile organ is that they are there to forestall glass target from sliding off a table .
" As a dusty Methedrine sit in a way temperature surround , the glass start to compile condensation . This condensation tend to slide down the side of the drinking glass and collect at the base of the glass , " Buster Ecks drop a line onQuora , adding " well if you put the glass on a flat smooth surface , the condensation will collect underneath the glass creating a layer of water between the chicken feed and control surface of the table . "
This may also may not be the main role for the ridges . As direct out by Twitter userGussterMolly , the " knurls " , as they are known , help forbid breakage .
" During normal handling of bottle , damage sire in the bearing surface is ordinarily confined to the tips of the knurls . In these situations , glass Earth’s surface strength is reduce but is concentrated at a placement where the stress indices are very down in the mouth for both interior pressure and bounder impact , " Dr Wenke Hu from American Glass Research explain in astudy .
" This is one of the master purpose of placing knurls on the bearing Earth’s surface of glass containers – to focus unavoidable hurt in regions where tensile stresses are significantly reduce . The irrefutable result is that breakage is typically averted . "
Nevertheless , a side effect of preventing trash smashage is that you’re able to skin salt into your solid food at alarming pep pill .
