Do you ever wonder what becomes of older technologies once considered the staple of traditional education? Chalk, blackboard and dusty erasers are becoming obsolete with the advance of the erasable white boards showing up in classrooms around the world. Here's what I think has happened to all the leftover chalk:

Chalk, in a rainbow of colors, was recycled and sent to gym classes and recess monitors everywhere so kids can enjoy a resurgence in the popular unplugged game of Hopscotch, a grade school favorite.

White chalk was given to police departments to help them outline bodies in crime scenes.

Tennis courts just wouldn't be the same without the out-of-bounds chalk outline.

Pool players can still use chalk to “chalk up” their pool sticks. Try taking a shot without a good chalking and see how well you do!

Let's not forget about weight lifters and gymnasts who need to make sure their hands don't slip during their events. The same goes for rock climbers.

City artists can use chalk to engage the world with their art without leaving a permanent mark. Kind of like building castles in the sand at the beach, no?

If that isn't enough for chalk-lovers, then plan a trip to “White Rocks,” the cliffs in County Antrim, Northern Ireland. They are made of chalk, a pure form of limestone.
