|Those cunning chemists in action's ink labs have come up with a new twist on the perennial search for an effective erasable pen. The ink laid |
down by the Frixion rollerball disappears under friction! The end of the pen has a hard plastic eraser, which when rubbed over the writing causes
the colour to disappear from the ink. You can then write over it again with the same pen.
How does it work? Metamocolor technology! 'Metamocolor' is a word entirely made up by action marketing people, but basically it's a type of
thermo-reactive ink. The heat generated by the friction causes the ink to become translucent (at 65?C fact-hounds!). Stick it in the freezer
(-20?C) and your scribblings will re-appear - albeit slightly faded. Ideal for secret messages and a lot easier than that old lemon juice and
candle flames malarkey.
Available in Black Blue Red Green Light Blue Purple Orange and Pink ink.
