This is a educational construction kit assembled from various materials (plastic, metal, etc.).
A cow usually stands around mooing and chewing, and nothing really happens--but if you look inside of it, there's really a lot going on! This lets you get a view inside a cow without getting on the bad side of local farmers. This kit allows you to take basically everything out of the cow and see where it goes and get an idea of how a cow works, and then you can test yourself by putting it back together. This is what a hamburger looks like when it's still alive. A stand is included.
