Icon 074. Blackboard
Listen carefully. Can you hear it? The screeeeeeeeeeeeeeeeeee of fingernails scraping across the blackboard? You know what that means? That's right. It's time for some learning. According to Wikipedia, blackboards have many advantages over their cousin, whiteboards:
- Chalk requires no special care; whiteboard markers must be capped or else they dry out.
- Chalk is an order of magnitude cheaper than whiteboard markers for a comparable amount of writing.
- It is easier to draw lines of different weights and thicknesses with chalk than with whiteboard markers.
- Chalk has a mild smell, whereas whiteboard markers often have a pungent odor.
- Chalk writing often provides better contrast than whiteboard markers.
Take that, whiteboards.
