Elaters are dead water-filled cells. Two forces are key here - cohesion between water molecules and adhesion between water Under dry conditions water is lost and the elater walls are pulled inwards. The elater walls have spiral bands of thickening so that as more water is lost the elaters assume a twisted form.
