I've always wanted to borrow the demo life vest to try putting the straps on myself. The older models are not straightforward looking - and I'm a boater and diver!
Anyway, those who want to practice interesting aviation emergency skills, including being explosively decompressed, should check out the FAA's CAMI
Aerospace Physiology Training Course.
You will need a class III medical (you should have a physical anyway, right?) and beards need to be shaved.
Great fun!
