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!

about 40 years too late lol
totally dumb, wouldn’t work anyway but, no one uses chalk, chalk is cheap, you could buy a lifetime supply of chalk for less than the cost of this crap. i have never been so unimpressed.
The main importance is the ALLERGIES PROTECTION. Even the “no scent” dry erase markers can affect people. My ex teacher couldn’t use dry erase markers (including no smell specialized for allergie prevention) would cause her to break out in hives, voice change.
Then the cool gadget would have kids’ attention. They’d be eager to clean the board in hopes to add to the chalk progression.

Just because the last school YOU attended didn’t use chalk, doesn’t mean “no one uses chalk.” And if you bothered to read the product description, there is no mention of the device being used to save money on chalk.
Then again, I wouldn’t expect anything less from someone who is so insecure, they need to name themselves “Mr. Right is Right Right Right.”
Yeah
Great idea! but who uses chalk anymore?
