A new way to play with erasable pens
this is the creative play of hot erasable pens that I saw two days ago, so I made a localized version myself. Pour hot water into the cup (more than 60 ℃), the color of the part painted with a thermal erasable pen will disappear, and ordinary handwriting will keep the color.
this is a lot of room for creativity, and it is very convenient to do, and everyone can try it.
the erasable ink contains many microcapsules sealed with "leuco dyes" and "chromogenic agents", which can be switched between colored and colorless states according to different temperature conditions. The eraser on the pen actually removes the handwriting by friction and heat, and if frozen in the refrigerator, the faded handwriting can be reappeared.
