I am an early childhood education teacher and I bought this human skull as a teaching model for students to show how my skull protects the brain. As we now prepare for our "Trike-A-Thon," this was a very good example of how a bike helmet protects the skull that protects the brain! The kids loved it! I especially loved the magnets that hold the skull and brain together! I'm sure I'll have more educational uses in the future! Thanks for a great product!
