With all the advertising about memory foam these days, it`s hard to imagine that this material has only been in existence for a little over 30 years.
It`s difficult to find an exact date when memory foam first came into being, but it was originally formulated during the early days of manned space flight.
Most likely, it was in the mid to late 1960`s.
The National Aeronautics & Space Administration, aka. NASA, needed a material that would cushion the astronauts from the unparalleled g-forces of launch and re-entry during space missions.
In response the their request, a material was produced, called visco-elastic memory foam.
I`ve seen dozens of articles explaining what visco-eelastic memory foam means and none of them has the same explanation.
The online dictionary gives no definition for the word visco, but the word is derived from viscous, which means "gummy or pasty." It is a cross between a solid and a liquid.
I think we all know what elastic means, but, again, the definition is, "being able to return to it`s original shape after being deformed."
Well...that`s enough of the grammar lesson. The point is that this material hadn`t existed before...it`s unique.
The whole idea, of showing a picture with a hand print, over the top of a memory foam mattress, is to illustrate that this material isn`t forcefully pushing against you.
That`s why it takes a while for the memory foam to react and slowly return, to it`s original shape, once the hand is removed.
Felt BoardOne of the most under estimated pieces of office equipment is the
Felt Board. This often unnoticed piece of equipment is probably looked at every day by every member of your staff, yet it is one of the most incongruous pieces of communication you have. A notice board is one of the cheapest yet most effective ways of communicating with in a work place. Hanging a
Felt Board in a prominent place can help you and your staff to pass information or post reminders with in the work place or even at home immediately. You can choose your
Felt Board in any size or any style, and always with in your budget. And if you can not find exactly the type of board your would
Grp ChimneyMy father told me the other day that he was trying to persuade my grandmother to have a
Grp Chimney in her house to replace the pot one that she used to have. He tried to explain to her that a
Grp Chimney is just as good as her old one was but it is much lighter and easier to install. However, my grandma would not be swayed. She kept asking him what was wrong with her original chimney and telling him that she did not think a
Grp Chimney could possibly be as good. My father really has got the patience of a saint with her. My mother says it is the first signs of senility in her but I am not so sure. I think she is naturally cantankerous and loves to argue the case about absolutely anything, even if she has not got a clue whether she is right or not as in this case. I told my father that he was his own worst enemy by actually telling her about it in the first place. If it were me, I would have just replaced the chimney without her knowing at all and she would never have been any the wiser. My father, though, is too honest for his own good, even though a little white lie would have been beneficial to everyone in this situation, he still could not bring himself to do it.
