A weird thing happens when ice freezes under the influence of an electric field. It turns out that electricity can make water strangely attractive. Yes, that was a pun. Proceed with caution.
One of the fun things about science is the many times you scoff at something being impossible, like say, lasers being able to erase metal from x-ray scans, and end up being a fool who was completely wrong about everything. A student in the UK wrote in to a physics site, asking if, since water molecules had a positive and negative side, it could be frozen into a magnet. Scoff, scoff, I thought. When water freezes, its molecules shift into a rigid lattice. Nothing like that could ever happen. Scoff.
