The dancing plumes

Swish, swish, swish, I have to run to escape the plumes of water cascading round and round over the small field. Innumerable water droplets journey together, upwards, upwards, then turning, falling, dissolving into a cloud of rain. Down below, the garden plants gratefully receive the life-giving water drops, capturing the droplets with their leaves. Some droplets continue, trickling down onto the bare umber soil underneath, wetting the soil and darkening it. Seeking its way into the hollows, seeping down, absorbed by the clayey, colloid substance that forms the fertile topsoil. Continue reading The dancing plumes

The healing water

The water flashes in the bottle, refracting the light from the sun. Veiled behind drops of condensation, a small pocket of air resides, between the surface of the water and the cap. Silvery, with a magical shimmer, water can sometimes look almost otherworldly. Like the healing elixir, brought to the companions of King Arthur, from the misty realms of Avalon.

The idea of some waters having a healing power can be traced back at least to ancient Greece. Equally old is the idea that hands-on healing (laying on of hands) may have a healing effect. In the 1960s, the Canadian biologist Bernard Grad (1920-2010) decided to investigate Continue reading The healing water

When water freezes

The temperature drops, water cools, and suddenly, there is a crest of ice on the surface, slowly growing and deepening. Soon it will be so hard that we can touch it without destroying it, and even walk on it. Anyone who has been skating on a lake will know that there is ice and there is ice. Sometimes clear, sometimes so filled with air bubbles as to be almost completely opaque.

The Swedish water investigator Gisela Ahlberg decided to explore this, and devised a method, together with her colleague Christina Weldero, to study natural waters by ice images. Continue reading When water freezes

Water’s pulse

Swish, swoosh, swish, swoosh, in a rhythmic pattern, the water swings to and fro in the vessel, a “flowform”, originally conceived by the British anthroposophist John Wilkes (1930-2011) in 1970 and since then developed into many shapes.

The incoming water flow, and the curved heart-shaped walls create the right conditions for a rhythmic flow to spontaneously emerge, to self-organize – a cooperative behaviour, which springs out naturally, effortlessly, from the conditions. The water molecules dance together. From vessel to vessel the dance continues, until the water reaches the pond below. Standing by the stair of flowforms, listening to the pulsating sound, it is as if it radiates tranquillity – a wild brook carved in stone. Continue reading Water’s pulse

The water vortex

Round and round, the vortex swirls in the bucket, mixing whatever is in it. Perhaps one of our most mundane acquaintances with water is stirring it, although we seldom give the process a closer look. Stirring vigorously will only create a blur. But the moment we leave water on its own for a while, the curved spiralling shapes appear and stabilize. The vortex funnel has chosen its preferred form.

Does water mind how we stir it? Will it behave differently afterwards depending on our movements? Looking at water merely as a dead substance, we tend to relegate such questions to the fairy tales. But even a fairy tale can turn out to be true. And in this case – just as a good fairytale should – it is about a land down under. Continue reading The water vortex
