HeatVanish Pen that Uses Heat to Erase Ink

Posted by: JackSimz , March 9, 2017

Believe it or not? This pen uses heat to erase ink. Engineers Jack and Patrick Aubin wanted to be able to erase ink without smudging. Their HeatVanish pens use heat-sensitive ink that disappears. Leaving a clean space behind.


Don’t worry, the pen automatically shuts off after 15 seconds. Its cap covers the switch so it won’t turn on in your pocket. It sells for $35 on Kickstarter.
