I thought this was worth a try as an exercise to see what it is like.I found that being face up was difficult to do without using a nasal plug to keep the water out. I found that the plugs I used leaked a bit causing me to "swollow"water and choke a bit,so I have gained a new respect for those who do the bath tub scenes.Over all it looks good but one thing I would not repeat to often.In real life, it would be an unpleasant way to be drowned!
