Solid-water films thinner than 0.8 nm were confined between the mercury surfaces of a squeezable tunnel junction at 265[plus minus]3 K. Uniaxial compression of the films was performed electrostatically by changing the junction bias. Mean compressive displacements were calculated from the nonlinear current response of the junction. Young's moduli of stable ice bilayers were estimated to be 134 MPa[plus minus]18%(stat)[plus minus]70%(sys), or about 1%--2% of the value of bulk ice I[sub [ital h]]. Moduli of ice double bilayers'' decreased with increasing film thickness, from a maximum of [similar to]20% of the bulk value.
