The NutCracker Effect

“Give me a lever long enough and a fulcrum on which to place it
and I shall move the world”

Archimedes
Greek: c. 287 BC – c. 212 BC

 

Archimedes the famous Greek mathematician first wrote about the power of the lever.

Kangapoda’s founder coined the term the “Nutcracker Effect” when it occurred to him that the bed was so tight at the sheet is tucked in because the sheet is acting like a lever in a nutcracker.  To help you visualize: imagine the sheet was a solid geometric plane of wood connected at the bottom of the bed with a hinge. You would never be willing to put your feet into that wooden crusher. Of course, a bed sheet—unlike a solid geometric plane of wood—has some give; but, down close to where it is tucked in it is surprisingly taut and unyielding. Ah-ha…now you’re beginning to understand the ‘nutcracker effect’!

  • The load is where the sheet is tucked-in under the heavy mattress and is held in place almost like a hinge. 
  • The fulcrum - or the nut - is your feet. OUCH!! 

  

 

Once upon a time 

People used their beds primarily to sleep, procreate, and recover when they were sick.

Today

The bed is the night time locus of TV-watching and surfing the web. This usage will only increase, as TVs are ubiquitous in the bedroom (well over 80%), TV programming is better than ever, and, in between (even during), we are tethered to our smart phones and tablets. 

The Kangapoda Solution

Kangapoda top sheets and blankets incorporate a patented ergonomic canopy. It lies flat when not in use to mimic a plain flat top covering; however, it expands and drapes the feet without tension when you are under the tucked in covers in a TV viewing position. Kangapoda’s approach eliminates the tension of a plain flat, top sheet and blanket. Thumbs Up for Feet Up!

 

Calf and foot cramping occur in a broad range of the population—from world class athletes, to middle aged people, to pregnant women. The unnatural position of having one’s feet constrained against a taut sheet for a period of time acts as a pseudo binding. This may lead to muscle contractions which can set off a sudden cramp or a spasm.
