Cheers for Cello Tape Day!
Here is a song about cello tape from my favorites, Flight of the Conchords.
On this day in history, cellophane tape was patented by Richard Drew, a banjo-playing inventor! In 1921, he went to work for the Minnesota Mining and Manufacturing Company, known as 3M, which at the time only manufactured sandpaper. He was product testing for Wetordry brand sandpaper at a local auto body shop when he noticed the auto painters were having a hard time making clean dividing lines on two-colour paint jobs. This dilemma inspired him to invent masking tape in 1925.”Scotch” tape got its name when, upon testing his new masking tape to determine how much adhesive to add, the body shop painter grew frustrated with the sample and told him to “take this tape back to those Scotch bosses of yours and tell them to put more adhesive on it”!
In Great Britian they use Sellotape like we use Scotch tape. The name Sellotape was derived from Cellophane, at that time a trademarked name, with the “C” changed to “S” so that the new name could be trademarked. Sellotape Original is made using cellulose film derived from wood pulp. The cellulose film decomposes naturally in soil, and is naturally easy tear and non-static. The Sellotape brand now covers a variety of tape products, and the word is frequently used to refer to other adhesive tapes in many countries due to its market exposure.

Below is the funniest thing I read about cellophane tape so far. It’s from unashamedramblings.blogspot.com Hilarious!
Thin plasticised adhesive strip generally wound around a toroidial prism of wood pulp which is used thus:
Find the end. This could prove rather more difficult than imagined as the four-dimensional Sellotape can displace its three-dimensional form with ease so as to eliminate its end totally.
Apply lateral tension to the end to separate a piece of the desired proportions and cut at the specified point. This could also prove difficult because the Sellotape is strong enough to blunt most earthly cutting instruments and despite which is rather less than eager to leave the come off its roll.
Some Sellotape has been observed to be maniacally happy and therefore to, upon the application of lateral tension, abruptly spring from its roll thus causing a twenty-metre piece to become detached. Attempt to force the tape to adhere to the desired surfaces. This could prove most difficult of all as the Sellotape will disobediently adhere to any other surface (including itself) other than the intended.
In a tour de force of office supply physics, researchers at the University of California, Los Angeles, have shown that it is possible to produce X-rays by simply unrolling Scotch tape.
In the issue of the journal Nature, Dr. Putterman and his colleagues report that surprisingly fierce flows of electrons were unleashed as the tape was unpeeled and its gooey adhesive snapped free of the surface. The electrical currents, in turn, generated strong, short bursts of X-rays — each burst, about a billionth of a second long, contained about 300,000 X-ray photons.

Now I have finger cancer.
