    selectively attaching or detaching two or more weights to form a composite weight having a total weight at least equal to said predetermined lift, each of the weights including means for tethering a balloon by means of a string; and

    tethering the lighter-than-air balloon to the composite weight by securing the string of the balloon to the tethering means of one of the weights,

    whereby the weight of a ballast for a balloon can have its weight incrementally adjusted to an amount just greater than the predetermined lift of the balloon thereby securely tethering the balloon to a surface, on which said composite weight is supported, without significantly exceeding the lift of the balloon.

    you could use anything heavier than air as ballast for a helium balloon, and adding ballast would make the balloon go down, removing it would make it go up
