Most schools have already made the switch to whiteboards, but there are still hundreds of thousands of schools that still use chalk and blackboards because it’s the cheaper option. So a neat alternative to plain old erasers? Chalkeeper is a very innovative way to contain chalk dust (which causes allergic reaction in many children) and reuse it. It is basically a duster that erases chalk from the blackboard and absorbs it into the system. When enough dust is collected, it molds it back to a piece of chalk…….kinda like a never ending chalk! Clever!
