A lot slower than when the cap is off. but it can still dry out.
Ink will be forced from the tip potentially causing quite a mess. If the cap is on, the cap could fill with ink potentially causing quite a mess.
color dry erase marker over it and then throw it in the washer
Because if it's NOT on the ink is exposed a little to air and other things like that dry it up but when you got a cap it covers it from that stuff. But if it stops working when it had a cap it might just be out of ink. :(
What happens when the cap is left off a "magic marker" is that the solvent or "carrier fluid" for the pigment (both of which comprise the ink) vaporizes and "goes away" leaving the marker dry and unusable. It should be noted that the ink in the marker is composed of two main parts: pigment and a carrier. The carrier is used to make the pigment "flow" onto the surface being marked, and then it goes away. If the cap is not put on tightly, the carrier doesn't know it isn't time to go away and it does, and this leaves the marker dry and ineffective. The liquid part of the ink containes toluene or xylene (or a combination of the two), both of which are highly volatile. There is also a flock of other things in there (in small quantities) to optimize the performance of the ink and help deposit the pigment or dye more effectively. Trying to "revive" the pen isn't worth the effort, because making a mixturte of the chemicals is difficult, expensive, and dangerous. It is more cost effective to replace the marker - and replace the cap when you're finished using it so it won't go the way of the first marker.
It doesn't it's just a myth or maybe the tight string makes it squeeze and the ink goes down to the point of the expo marker
no you cant because the marker ink will wear off onto the surface of a desk or so on.
He was my mother's husband, later in life. He was a chemist. As far as I know, yes, he did claim to invent the ink used in dry erase markers.
it barfs ink
yes you can!
The ink of a marker used to be made of toluene and xylene. These substances were found to be quite harmful so now the ink is usually made out of alcohols such as 1-propanol, 1-butanol, diacetone alcohol and cresois.
