Featuring... Utility knife caps - Many utility knife blades have to be snapped off in order to have a nice new sharp blades, but a lot of people go out of their way to grab pliers or gloves to snap off the blade. There's no need to go out of your way though, because there's a break-off slot right here on the back. Little hole between lens and flash on an iphone - If you have one of the latest iphone models you've probably seen the little hole between the flash and the lens and wondered what it's for. Its actually a the tertiary microphone - yes, thats right, the Iphone has 3 microphones! Buttons on lids – indicate drink type - As a child these buttons on drink lids can provide you with an easy 5 minutes of entertainment, but they actually serve a practical function too. Beer bottle neck - The neck of a bottle of beer isn't just a sleek design feature or a convenient alleyway for the beer to make its way into your mouth. Metal plate on a stapler - Most of you staple things without regard to the way in which you're binding the thing that's being stapled. There are actually two ways to staple things. The way you're probably familiar with is the permanent method of stapling, it's the default setting on a stapler. The hole at the end of a lollipop stick - Even though this hole at the end of a lollipop stick looks like a hole on a flute or whistle, it isn't there to whistle through when you've finished your lolipop. Disher Scoops - Everyone know what these Ice cream scoops are used for, I mean... its kinda in the name. However, you might be surprised to know that they come in a multitude of different colours, but these colours aren't for aesthetics. - Lids on drinks – can be used as coaster - Lids for takeaway drinks are actually a lot more versatile than you'd first think, as not only do they stop you from spilling sticky liquid all over yourself, but they also double up as a coaster. Hole in pen cap – stop people from suffocating - A common misconception about the hole in the end of a ball point pen lid is that it is there to stop the ink from drying up... or it's a whistle. Traffic Lights Hidden Dial - You may not have noticed this spinning dial under the button at a pedestrian crossing before as its rather hidden, but it has an interesting use. If you never noticed it then take a guess as to what its for, I'll be impressed if you can figure it out.
