A 2011 study by musicologists Michael Oehler and Christoph Reuter led its authors to hypothesize that the unpleasantness of this sound is caused by acoustic resonance due to the shape of the human ear canal which amplifies certain frequencies, especially those in the range of 2000 to 4000 Hz (the median pitches …

Misophonia is a disorder in which certain sounds trigger emotional or physiological responses that some might perceive as unreasonable given the circumstance. Those who have misophonia might describe it as when a sound “drives you crazy.” Their reactions can range from anger and annoyance to panic and the need to flee.

Certain people may have a sensory deficit related to the sound or feel of Styrofoam. “This is a neurological disorder, where faulty brain wiring causes a particular aversion towards the feel, sound, or appearance of Styrofoam,” Neo says.

Brain imaging shows that when we hear an unpleasant noise, the amygdala (active in processing emotions) adjusts the response of the auditory cortex (part of the brain that processes sound) which heightens activity and triggers a negative emotional reaction. …

This stranger claims it’s because an electric charge builds up due to the electrically insulating properties of the styrofoam, and this charge is transferred painfully to your body through your teeth.

Styrene is toxic to humans and a major pollutant. What Can I Do? Avoid using Styrofoam for hot/acidic food storage. While at work or out and about, bring your own mug for coffee and other hot beverages.

What happens when you ingest hot liquids and possibly hot food from polystyrene foam cups and plates is that the styrene may leach out of the foam food service ware and into our bodies. Styrene is such a problematic chemical, it’s included on the Hazardous 100+ list that we’re encouraging retailers to move away from.

It occurs because of intermolecular forces between the liquid and surrounding solid surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension (which is caused by cohesion and adhesive forces between the liquid and container act to lift the liquid.

and the size of the hole. Leak rate = pressure x size / loss factor. If the pressure reaches zero, then the leak rate will also reach zero, and hence for a styrofoam cup, dropping freely to the ground in a vacuum, no water will leak through the hole.

Styrofoam is an insulator, making it very poor at conducting heat. Heat can’t pass on through to the water, so the Styrofoam disintegrates. Now go ahead and bet a friend or family member that you can boil water in a Styrofoam cup.

Toxicity: Styrofoam is considered non-toxic when eaten. Expected symptoms: No symptoms are anticipated when a piece of styrofoam is accidentally ingested, but large pieces can cause choking. What to do: Give your child a drink of water to wash the styrofoam down to the stomach.

It doesn’t have to digest. If they were reasonably able to choke it down, it will likely be passed in the stool. Might still be nasty poopy styrofoam chunks though. Don’t take anything that will make you have stronger/faster bowel movements though, if the heat was enough to melt it, there could be some sharp parts….

The manufacturing of polystyrene requires the use of hydrocarbons such as styrene and benzene. These hydrocarbons are released into the air and react with nitrogen oxides to produce ground-level ozone, a hazardous air pollutant. Ground-level ozone can impair lung function and lead to respiratory illness.

To throw away Styrofoam, remove any recyclable pieces, then break down sheets or blocks into smaller bits you can put in your regular trash can. To recycle, make sure you have plain white Styrofoam marked with the triangular recycling symbol. Contact local agencies to see if they’ll take it.

Ways to Reuse Styrofoam Packing Peanuts

• Reuse as Packing Peanuts. There’s no reason why styrofoam peanuts can’t be reused as what they were made for before!
• Stuffing.
• Alternative to Ice.
• Plant Pot Fillers.
• Tighten Loose Screws.
• Christmas Tree Tinsel.

Here are a few easy ways to reuse your Styrofoam cooler and give it a brand-new life.

1. Make a Cheap Air Conditioner.
2. Use It as a Grocery Holder.
3. Create an Outdoor Cat House.
4. Build a Compost Bin.
5. Pot Your Plants.

Adding a few inches of foam peanuts or chunks in the bottom of the container reduces the amount of soil needed to fill the planter. Also, the foam keeps soil from washing out of the drainage holes while assisting with drainage by keeping the soil from compacting at the bottom of the pot.

You can use a regular craft sealant such as Mod Podge, or you can target the styrofoam specifically and use something like Foam Finish. Apply the sealant using a foam brush or regular paint brush and then let it dry completely before painting the styrofoam.
