Cold clusters

Nanoclusters of water show a steady increase in internal energy relative to temperature that matches that of bulk ice at low temperatures. But at around 100 kelvins, this rate of increase changes drastically for the nanoparticles. Researchers think this sudden increase in internal energy compared to temperature indicates a phase shift of the water clusters, from solid to liquid. Credit: Hock et al./PRL 2009

Such finding can be understood intuitively by the fact, inside of small droplets of water, the hydrostatic pressure is much larger due the higher curvature of water surface, then in the bulk. Higher pressure leads to melting of ice at lower temperature.

In analogous way, the small radius of tiny neutron droplet formed in LHC accelerator can lead to formation of strangelets, i.e. tiny neutron stars, which will be stabilized not by gravitational field, but their surface tension pressure. This can lead to disastrous consequences even without presence of true black holes.

As another evidence of water clusters can serve the electrolysis of water by radiowaves. Water clusters are behaving like jelly and they're probably responsible for many anomalous properties of water, the water memory effects in particular.
