A quantitative theory of the effects of mental influence outside the body, based on the idea that such influence consists of the ordering of random fluctuations within the limits of the uncertainty principle, is used to predict the effects of ordered air molecules on a tumbling cube. If the influence can act throughout the first tumble of a cube, the pressure necessary to produce the deviation effects achieved by Forwald (1959, 1969) is estimated to be 1.45 x 10-5 dyne/cm2. The number of molecules which must be simultaneously influenced to produce this pressure is 2.41 x 105. The trajectory of a tumbling cube must have a minimum number of steps s0 in order for any substantial amount of magnification of a change in its trajectory to occur. (A step is a tumble from one corner to another.) When mental effects are produced by ordered molecules, s0 depends logarithmically on cube parameters (mass, length of a side, velocity), the pressure of the surrounding gas, and the number of molecules a person can simultaneously influence. If a cube of mass M and half-length b is compared to a cube with mass M1 and half-length b1, and all other parameters are constant, then s0(M,b) - s0(M1,b1) = log2(Mb12/M1b2). If different numbers of cubes n and n1 are influenced, with all other parameters constant, then s0(n) - s0(n1) = log2(n/n1). If values for s0 are compared at pressures P and P1, with all other parameters constant, then s0(P) - s0(P1) = log2(P1/P).
