From Dust to No-Dust

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!

  • Paulo Corceiro says:

    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.

  • Jack says:

    the chalk’s ingredient is CaSO4. O(∩_∩)O~

  • Jancarius says:

    That sucks, I always loved getting picked to go knock out the chalk erasers in elementary.

  • tristan says:

    but chalk sticks are cured/baked in an oven to harden

  • jack black says:

    no one uses chalk any more dry erase boards are what i see most.

  • Tim says:

    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.

  • Ole Gus says:

    Tasmanian devils are not extinct… You mean the Thylacene?

  • JakeWiz says:

    This would have been sweet if it was made 20 years ago when people used chalk boards

  • maxy says:

    erm… actually it’s CaCO3…

  • Proxy List says:

    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.

  • Joel says:

    Who uses chalk?

  • Rachel says:

    Only problem… I don’t know of a single school that uses chalkboards. It’s all Whiteboards and SmartBoards now.

  • Jake says:

    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.

  • Christian says:

    Very clever idea. Would have veen extremely useful if white boards werent replacing chalkboards

  • Mark says:

    erm, great until you use multi coloured chalks and end up with a new dirty brownish chalk stick

  • Jed says:

    This would of been cool 20 years ago…

  • manish.kumar says:

    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..:)

  • Hunter says:

    Great idea! but who uses chalk anymore?

  • J says:

    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.

    • ShieldsCW says:

      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
