    any where is fine. have a larger container than is holding the blue
    pickle (spent when deep blue- alternatively bottle in a Kimex jar and
    use for copper plating!) as the reaction causes a volcanic foaming
    ooze that will invariably spill out of all but the largest vessel you
    own- I place it in my wash out sink and just let it do its thing
    until the foaming stops then run clear water behind it for a moment
    to insure no baking soda that hasn't dissolved reacts with the next
    mouthwash use!..( it' makes a great kids volcano science project too-
    give the kid a set of goggles, gloves and an apron, wood or masonite
    base, newsprint or celuclay for the mache', and silicone caulk or tub
    sealer and in a jar, a half cup of the spent sparex ( not sulfuric
    acid even if spent) and in a small container or baggie, about two
    tablespoons of bicarbonate of soda and after the papier mache volcano
    is made -placing a length of discarded/recycled plastic pipe centred
    as the chamber & silicone caulked onto the base of the whole project,
    add the spent pickle(you can leave it in the baby food jar), add the
    baking soda and voila, instant white lava flow... you can rig all
    sorts of time delayed contraptions for the soda (rice paper wafers
    work great, or weighted and switched filter paper), and colour it
    with red orange dry food colourant,,but that's another channel).
    thanks for neutralizing
