  We experimentally investigate the Leidenfrost effect at pressures ranging
from 1 to 0.05 atmospheric pressure. As a direct consequence of the
Clausius-Clapeyron phase diagram of water, the droplet temperature can be at
ambient temperature in a non-sophisticated lab environment. Furthermore, the
lifetime of the Leidenfrost droplet is significantly increased in this low
pressure environment. The temperature and pressure dependance of the
evaporation rate are successfully tested against a recently proposed model.
These results may pave a way to reach efficient Leidenfrost micro-fluidic and
milli-fluidic applications.
