Cuttable Jelly Watermelon Toy

A browser-based soft-body jelly watermelon toy. Draw a line with a steel knife to slice the translucent melon wedge. The knife presses a groove into the jelly before it breaks through. Each cut piece can be grabbed, stretched, cut again, and keeps wobbling. The rendering uses refraction, absorption, and scattering in a magazine-style "Material Studies" page layout, about 17 seconds long. Suited to physics simulation demos and creative interactive shorts.
