Neptune's necklace/Aphrodite's pearls
Penny from lifeonthecutoff wrote about people's compulsion to pop all the cells in bubblewrap.
I decided to make big trails of Neptune's necklace out of sand, and leave them there for the incoming tide to sculpt and eventually take away.
In the course of my research I gathered this seaweed - also known as 'bladderwort kelp', and learned about how it mates with itself. On the surface of the individual 'bladders' lie the sexual cells. When the conditions are right, the sperm and egg cells all release together in one great burst, and fertilisation occurs. Then at high tide, the fertilised eggs are carried away.
Well, I had quite a pile in my fridge that I'd brought home, luckily placed into a plastic bag, because after a while I heard a strange noise coming from the fridge: a kind of hissing and exploding. I looked inside, and discovered that the pesky kelp was mating with itself in there. Something about the fridge must have created the perfect conditions. (I see from my notes that being cold and dry triggers reproduction).
