  We present collision experiments of centimetre projectiles on to decimetre
targets, both made up of solid ice, at velocities of $15\,\mathrm{m\,s^{-1}}$
to $45\,\mathrm{m\,s^{-1}}$ at an average temperature of
$\mathrm{T_{avg}}=255.8\pm0.7\,\mathrm{K}$. In these collisions the centimetre
body gets disrupted and part of it sticks to the target. This behaviour can be
observed up to an upper threshold, that depends on the projectile size, beyond
which there is no mass transfer. In collisions of small particles, as produced
by the disruption of the centimetre projectiles, we also find mass transfer to
the target. In this way the larger body can gain mass, although the efficiency
of the initial mass transfer is rather low. These collision results can be
applied to planetesimal formation near the snowline, where evaporation and
condensation is expected to produce solid ice. In free fall collisions at
velocities up to about $7\,\mathrm{m\,s^{-1}}$, we investigated the threshold
to fragmentation and coefficient of restitution of centimetre ice spheres.
