Have you ever noticed a dent at the bottom of wine bottles, jam jars and even your favourite Nutella jar? These days even normal mineral water bottles have it. This seemingly useless dent is not only a design feature, it has functional purposes as well.
Remember that one time when you balanced a bottle on your fingers? Well, this small dent was working hard to make sure the bottle does not fall off. But, has it ever crossed your mind if there are more reasons why most bottles and jars have a dent at the bottom?
Well, here are some answers:
1. It makes it easier for you to hold the bottle. The dent acts as a spot where you can place your palm or thumb and use the other fingers to wrap around the base.
2. It provides an optical illusion to your eyes, thus, tricking you into thinking the bottle is bigger than the standard size.
3. Optical illusion also saves up to 57 grams of the content inside the bottle, thereby deceiving you to think that there is more content than there actually is.
4. It adds strength to the base of bottles and jars, keeping them from bursting due to the high pressure in which the wine or jam is kept. It also keeps the content intact and fresh.
5. It helps the sediment deposit around the circumference of the dent in the bottle, thereby stopping the deposit from getting mixed with the content. This explains why expensive jam, Nutella and wine bottles have a deeper dent than their cheaper kinds.
6. It makes it effortless for you to clean the bottle because water can easily spread around the bottle in an even manner.
7. It increases the contact surface between the content like wine and the ice, thereby keeping the drink cool. Wine bottles are normally kept in ice buckets and better contact surface with the ice allows the wine to cool faster and stay chillier.
8. The traditional way of stacking wine bottles require keeping the nose of one on the dent of another, which is why they always have a dent.
9. It prevents the bottle from resonating, keeping it from breaking during transportation or shipping.
10. As opposed to a flat-bottom bottle, dents prevent the bottle from toppling over because it provides more stability.
Quite an eye-opener?
