  1. Ken Tucknott :

    Frank, I think I must be missing something here but,
    If the glasses are numbered from the left & the glasses with liquid in them are regarded as “full”,
    pick up glass number 5, tip its contents into empty glass number 2 and then
    replace the now empty glass number 5 in it’s original position?
