Tip for Whiteboard Teaching

For those of you who like to use the whiteboard to aid in teaching, there is the once in a blue moon occurrence of accidentally writing on the board with a permanent marker instead of the dry erase markers. Yikes!

Not to worry though...if there is a spray bottle with ethanol (alcohol) near the whiteboard, you can use that to erase the permanent marker.

BUT in the unfortunate event that you don't have ethanol nearby, this video shows a quick alternative to removing permanent marker ink from a whiteboard.
