    If no physical touching allowed then we can't physically separate them.
    Separating the salt and pepper pots is aloud?

    Are the grains of equal size?

    Pepper and salt have different melting points ... is that possible?

    different mass?

    what is your method of separation?

    put some heat on it and evaporate chillies (collect somewhere : flash -- no touching)

    2) Use air force...

    Pepper doesn't melt.

    sounds impossible..

    I am considering something 1400 deg C or over...

    I thought pepper has lower melting point than salt
    (don't know what kind of bonds it has ... )

    yeee but pepper which origins from a plant when heated
    comes in contact with the oxigen in the air
    and gets burned

    which is not aloud

    Take a balloon and rub it on a wool sweater, then hold it right above the mixture.

    :biggrin: Wouldn't that would be more along the lines of incineration?
