Rubber bands are a ubiquitous office supply. They can be used for organizing paperwork, keeping food fresh, or even shooting at coworkers. However, despite their seemingly harmless appearance, rubber bands have been known to cause immense pain when snapped against the skin.
So why do rubber bands hurt so much? We will explore the science behind this painful phenomenon in this article.
The Anatomy of Rubber
Before we can understand why rubber bands hurt, we need to understand what they’re made of. Rubber is a polymer that’s derived from latex, which comes from the sap of certain trees like hevea brasiliensis. Through a process called vulcanization (which involves heating sulfur and other chemicals with raw latex), natural rubber becomes the durable material that we know today.
But what makes rubber bands special? It all comes down to their elasticity.
When you stretch a rubber band, it stores energy as its molecules lengthen and pull apart from each other. This potential energy is waiting to be released – just like how pulling back on a slingshot creates tension until you let go and launch the projectile forward.
However,it’s not just about stretching: even if you don’t move your fingers after positioning them around some part of your skin (like an arm), eventually enough stretch builds up in one area such that there appears top be movement – this sensation is called cutaneous Rabbit Syndrome!
In terms of physics,elastic deformation occurs when changes in shape are reversible under small stresses! Therefore,it follows that rubber elasticity exists due to physical changes being produced ing individual polymer chains- these long chains interact weakly thereby causing thermodynamically elastic properties.Take for instancebetter formation structures=minor changes in chain conformations(moisture) affects drastically.
Snap Back:The Science Behind The Pain
One of life’s greatest pleasures is snapping rubber bands at your coworkers when the opportunity arises. But have you ever noticed how much that sting after the snap lasts? It can even leave a mark!
So why does it hurt so much? The answer lies in physics.
When you let go of a stretched rubber band, it snaps back to its original shape with impressive force. This transfer of energy happens quickly and violently, making it feel like you’ve been hit by a tiny whip.
But don’t worry – elastic deformation will only cease between external stress relevant axes! Essentially this means if you avoid pulling on an “infinitely small” object,stress can still be induced but it won’t deform.Phew
Another factor to consider is the area being impacted: let’s say You stretch out one mini-rubber-band as far as possible and release;you might have very little sensation because surface area on your skin is evenly distributed.However inserting that same amount(rubband) inside another thicker rubband could make for quite a new experience !
Pain Is All In The Mind
We’ve all heard the expression “pain is all in your head”. But when we slap our wrists with some elastic material, what makes us feel pain?
Turns out,it has everything to do with thermoreceptors– These are receptors found underneath our skin which respond specifically to temperature variation (via thermal conduction).Basically they help send information(electric signals) regarding temperature changes in order produce sensations like ‘heat’ or ‘cold’.
Think about burning yourself accidentally ,the first sensation experienced wont exactly come across as pain,but through time thermoreceptors would have picked up changes indicative of tissue destruction thus sending those messages(painful feeling).
When a rubber band hits your skin,since atoms tightly packed together(hardness),it sends contractions (/vibrations )through the skin via thermal conduction;This isthe equivalent to a temperature change!(millimeters of tissue can move)Translation our thermoreceptor picks up the sensation,sending signals receptors in spinal cord as well higher order brain areas(lo and behold pain!)
Location, Location, Location
As far as location goes,it’s not just about what part of your body is hit– it’s also about how thick or thin that area is.There are parts like forehead having more nerve endings (per cubic millimeter) therefore an elastic sting would be felt much more intensely!
We’ve talked about why rubber bands hurt so much – but surely there are ways to avoid the pain?
Here are some safety tips:
Use A Thicker Band
The thicker the band, the less it will snap back with force(mostly because since it requires more kinetic energy applied before attaining equal peel off thus hitting you with lighter momentus effect); Making sure limbs/wrists/forehead(sensitive parts)are targeted by extra-thick rubbers means offering yourself some preventive measures from painful matches.
Avoid Stretching It Too Much
“The longer/higher the stress point,the larger magnitudes produced under strain” – Simply watch what rubber-band experts do on YouTube,and stretch(relatively small amount recommended max 12x its initial lengthiness)- elasticity ultimately fades over time_ meaning too many stretches could cause cracks(lesser life span-nuclear used car engine lot people ).
Much like any regular exercise regime where warm-ups should precede heavier “lifts”,One may consider a slow pull on their wrist,half-scoring medical appointments then slowly increasing pressure after every pull until fusing become tight enough.
Finally: taking breaks can help decrease propensity getting out-of-hand movements when face-to-face battles ensue
Rubber bands may seem harmless,but one wrong flick and these little loops of rubber can cause immense pain.They’re made of natural material known for being durable,and stretchy with properties that if well understood,can be utilized to make the most out of this common office accessory
Just remember – safety first. Use thicker bands or try not stretching too much.Next time someone tries flicking one against you,you’ll actually know why it hurt.
