Why Are Crisp Packets So Loud?

The rustling of crisp packets gives away where you are eating and is annoying. But there is a reason for this: it has to do with basic psychology. According to Charles Spence, an Oxford University professor of experimental psychology, the sound of a crisp packet rustling makes people think it tastes better.

Crisp packets make you think they’re crunchier

Crisp packets aren’t crunchier. They are just packaged differently. Some crisp packets are biodegradable, but they aren’t. That’s because they don’t decompose in the environment, a process that’s harmful to wildlife. Some manufacturers are trying to create alternative packaging options. Frito Lay, for example, tried to create compostable crisp packets in 2010. These packets were made from poly-lactic acid, a corn-based biopolymer. However, after a year, they had to withdraw them from the market. This is mainly due to noise issues.

Crisp packets are also hard to recycle. The plastic from them ends up in our rivers, seas and beaches. This plastic can be harmful to marine life and can pollute the ecosystem. In 2018, a Walkers crisp packet was found on a beach in Cornwall. Even though it had been exposed to the elements for three decades, it was still almost intact.

Plastics make noise when crushed

Many plastics make a noise when crushed or opened. When you cut a piece of candy, for example, you will hear the plastic wrapper making a clattering noise. At the movies, plastic candy wrappers are a constant source of noise that can be irritating to moviegoers. Similar noises also come from many types of paper.

Most plastic packaging is made of polymers such as polyethylene, cellophane, and mylar. While these materials are tough and durable, they are not flexible like rubber or cloth. The creases in the plastic material are responsible for the noise they make. Because of this, theatergoers cannot do much to minimize the volume of the noise. This has led several physicists to discuss the noise from crushed plastic wrappers.

Candy wrappers

If you’ve ever walked into a movie theater and heard a popcorn or candy bar pop, you know how loud these packaging materials are. However, you may not know exactly why they make such a noise. To answer this question, scientists from the National Institute of Standards and Technology studied sound waves generated when candy bars are wrapped. The researchers discovered that the sound is generated by pops and clicks that occur as the wrapping material is pulled apart. Although theatergoers cannot reduce the loudness of these pops, they can take certain steps to decrease the noise levels.

First of all, it’s important to know that many kinds of plastics make noises when crushed or opened. It’s no different for candy wrapped in plastic. The noise that it makes when ripped or removed is similar to that produced when a boulder is rolled over uneven terrain.


If you’ve ever been to a movie theater, you know how loud the chip packets can be. While it may seem inconvenient, the noises can make you more likely to enjoy your snack. In fact, studies show that loud noises improve the taste of potato chips. In one study, Oxford University professor Charles Spence found that those who listened to the loud noises of chip packets experienced better taste.

If you want to avoid disturbing others, try eating chips in a quiet place. If you’re eating in public, it is best to bring your bag with you, or wait until someone is distracted to avoid obnoxious noises. Also, if you’re eating a chip, try to chew it thoroughly until you’re ready to swallow. By moving it deeper into your mouth, you’ll be less likely to disturb others by your snack.

Tampon wrappers make a lot of noise. This is especially true in the bathroom. Fortunately, there are ways to hide them. There are phrases that tell people not to talk about tampons, or they can even tell someone that it is a period. In this article, we’ll take a look at these phrases.

Tampons are often disposed of in the toilet. But they can clog the pipes and cause blockages. If you’re visiting a public restroom, make sure to wrap them in toilet paper before flushing them. If you’re not able to find a bin, you can always wrap them in toilet paper and place them in the trash. But, please remember not to flush used tampons in the toilet! They can ruin the septic system.

Tampons are also associated with Toxic Shock Syndrome (TSS). This is an extremely rare condition, but can have serious consequences if you’re not careful. Warning signs of TSS include sudden fever, vomiting, diarrhea, a sunburn rash, and dizziness. If you experience any of these symptoms, you should seek medical help immediately. Although rare, TSS is a serious condition that can even lead to death.
