Brass and Copper Handles - Undoubtedly you're scratching your head about this one.... like - what could be the underlying purpose of a handle, we all know they're used to open doors, right? True, but the reason they're often made of brass and copper has a purpose in itself. Golf Ball Dimples - The reason golf balls look like they're constantly ridden with acne is quite an interesting one. Golfers realised than older balls that had been beat up with slices, nicks and bumps seemed to actually fly further than ones which were new and perfectly smooth. Since seeing is believing, golfers eventually preferred to use older balls to newer ones and that got the attention of golf ball designers. They realised that the cuts and bumps acted as 'turbulators' inducing turbulence in the layer of air next to the ball. Effectively, in some situations this turbulent boundary layer actually reduces drag, allowing the ball to travel faster and to a greater distance. Brown Coloured glass bottles - Just like the copper and brass handles, the colour of beer bottles is an incredibly important and often overlooked feature of your favourite brew. Brewers actually choose brown-coloured glass to help block out ultraviolet light from the sun. Without this coloured glass a beer will go foul sooner than with it, and thus will lead to it smelling and tasting rather foul. The 57 on a heinz bottle - The number 57 is a lucky number chosen by henry heinz in 1896 which he started using in all his advertising, using the slogan '57 varieties'. However, according to heinz, only 11% of people know the secret behind why it is placed on the neck of heinz bottles. Apparently, its used as a way to get heinz ketchup out of the bottle. The '57' print locates the 'sweet spot' of the bottle. To release ketchup faster from the bottle, it is suggested that you apply a firm tap to this number. This my friends is a game changer - you'll spend less time shaking, bashing and wiggling a knife around the bottle. Prescription bottle caps - These things look odd, but they're actually really useful. Most medication has child lock bottle caps, so that babies don't start popping unwanted pills while your not looking. However, when the cap petrudes like this it means that the cap can actually be reversed, un-childproofing your prescription bottle for that little extra convenience of not having to push down whilst you screw off the cap. After all, thats why the cap is threaded. Jean Studs and Small Pockets - Most people probably have no idea what's up with the strange design quirks of jeans. For instance, this peculiar small pocket within the larger one of your jeans, which is sometimes assumed to be a coin pocket despite making it nearly impossible to retrieve your loose change. Interestingly, until recently it did serve a good purpose and was first seen on levi jeans back in 1873. Measuring Tape hole and serrated edge - These are pretty simply but equally interesting design details. This hole here actually exists so that you can hook onto nails or screws to measure safely without the tape measure slipping. Winglets - These aerodynamic curved wing tips were developed by a nasa engineer in the 70s who took inspiration from birds that curl their wingtip feathers while flying. They may come in different shapes and sizes, depending on the shape of the aircraft, and are usually decorated with a logo, website or company branding, but they're not actually for aesthetics.
