A method to prepare a windowless, self-supporting and low-cost ice target is described. The produced target was successfully used to measure the spectra of inelastic proton scattering from 16O. An ice target of about 30 mg/cm2 worked stably. The target thickness was monitored for 7 hours by measuring p+p elastic scattering and no meaningful variation of the thickness was observed. No obvious effect of contaminations due to the congelation of residual gases on the target was detected. Since a thin ice target was made, measurements of charged decay particles in coincidence with inelastically scattered particles are possible.
