1DS had a blast exploring matter last week as we sought to find out whether the green, gooey substance we made from scratch was a solid or a liquid.  It certainly exhibited qualities of both...at times flowing and taking the shape of its container and at others, holding its own shape with identifiable sides and corners.  But not for long!  It moved from one to the other, with oozing ease!
