If you took two clean, polished, identical wrenches into space, and then touched them together, you would end up with one large, misshapen wrench. The two wrenches would fuse together as if they'd been welded, without any application of heat or any pressure on your part. This is an effect known as 'cold welding'.
Cold welding occurs because space is a vacuum. It couldn't be achieved on Earth because metals form a protective oxide layer from being exposed to the atmosphere. In space, with no atmosphere, there is no way of the atoms from the two individual wrenches 'knowing' that they're not part of the same wrench, so they bond together and fuse. It's an issue that spacecraft and satellite designers have to bear in mind - and possibly also has beneficial implications for steel construction within a vacuum on Earth.
For the past few years, we've been seeing more and more food halls dominate the retail industry. The craze has swept Los Angeles and New York by storm and is now making its way to Miami. In Magic City alone, ten of these food parks have opened just recently. The mania is even set to triple in size by the year 2020.
Now more than ever, more people have been adopting a vegan lifestyle. A survey in the United Kingdom reveals that 3.5 million residents have turned vegan, while 20 percent have at least tried the concept. People are now wanting to cut down on meat, and the food industry is giving in to the demand. Even wineries have started stocking up on vegan wines.
Due to increased awareness and desire to help the environment, companies have become more committed to eco-friendly food packaging. Previously, companies didnt care much about producing a ton of waste; but now, efforts to reuse, reduce, and recycle are much more apparent. For instance, PepsiCo has committed to creating completely recyclable packaging by the year 2025.
Who would have thought that young millennials would be into rum? These barrel-aged, small-batch rums are the latest trend in booze, and now even British companies such as Essexs English Spirit are joining in. The spirit is one of the most popular and versatile forms of alcohol, whether it be sweet or strong, dark or white, neat with ice or served with coke.
Nowadays, people have become more accepting of imperfection; when it comes to fresh produce that is. Imperfect Produce is just one of the grocery delivery companies that serve physically flawed fruits and vegetables. This effort is geared toward reducing waste, and the disfigured foods are often turned into hummus, crisps, and juices.
Various Asian restaurants have been popping up recently, and Sri Lankan cuisine is slowly making its way to the western palate.
