Heads

No, this isn't what happens to students who misbehave. These dolls' heads are used in a (somewhat gruesome) demonstration of what would happen to a astronaut whose helmet lost pressure during a space walk.  (They are filled with shaving foam, then put in a container from which the air is extracted.)

Last teaching day of term today.  Open day tomorrow, then upper school prizegiving. Not much of importance on Friday.
