EG:As a species, we're drawn to water. It keeps us alive, but that doesn't explain our fascination with its tactile properties. Show us a pool of water and we want to dive in, splash around or at least have a little paddle. More than that, we're captivated by the way water moves. Children are still endlessly amused by the way an empty squeezy bottle can be transformed into an impromptu water pistol, and even the most stoic of adults can't resist a playful squirt with the hosepipe while tending to the shrubbery.
