This water cage ice model illustrates the hexagonal crystal lattice structure and consists of 20 water molecules formed into a "cage " called a methane clathrate, ice clathrate or clathrate hydrate. These gas hydrates usually form two crystal lattice cubic structures. Type I (aka sI) with a unit cell of 46 water molecules, that form 2 small and 6 large cages from the pentagonal dodecahedron subunit shown in the image.
Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) parts for 30+ years (scroll down to see "Skeletal (Orbit/Minit) and are compatible with every molecular model kit we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.
For the sake of clarity, the hydrogen atoms have been left off & there is no methane molecule shown trapped inside.
