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!

Problem solved!
This is clever!
This is cool, despite the reduced use of chalk against the white board with markers or even face to interactive whiteboards.
I’ve think of this inwention one years ago,the chalk’s ingredient is Ca(OH)2 ,raw material is CaO.It’s hard to realize this product,the fan can no get in the dust, and the mold is not a suit way to squeeze out the chalk.
the chalk’s ingredient is CaSO4. O(∩_∩)O~
That sucks, I always loved getting picked to go knock out the chalk erasers in elementary.
but chalk sticks are cured/baked in an oven to harden
no one uses chalk any more dry erase boards are what i see most.
Nice design and clever concept. However, in Australia blackboards/chalkboards have gone the way of the Tasmanian Devil. Extinct. The last chalkboard I remember seeing in use was almost 12 years ago.
Tasmanian devils are not extinct… You mean the Thylacene?
This would have been sweet if it was made 20 years ago when people used chalk boards
erm… actually it’s CaCO3…
I didn’t know people could be alergic to chalk. There was no one in our School but if this helps, nice product. Although I think it came too late.
Who uses chalk?
Only problem… I don’t know of a single school that uses chalkboards. It’s all Whiteboards and SmartBoards now.
I think it’s an interesting product! I would like to point out that I attend MIT and even we still use chalk boards 😛
I, for one, think they’re very classy.
Very clever idea. Would have veen extremely useful if white boards werent replacing chalkboards
erm, great until you use multi coloured chalks and end up with a new dirty brownish chalk stick
This would of been cool 20 years ago…
what for the chalk that blow off during writing and affect the teachers.
btw who uses chalk in today’s classroom.
every blackboard is now replaced with white board and we use marker instead.Still nice try..:)
Great idea! but who uses chalk anymore?
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?
