I'm not thinking about tank accidents. I've read stuff about bone formation - muscle formation etc that would preclude the pressure of any kind of depth. As Kat pointed out - are 3rd graders -or 4th, 5th etc really capable of understanding Boyles Law? Have they really got the conceptualization skills necessary? Are they emotionally aware enough to make the right decisions?Jaronoff:I think that all tanks now have burst disks, and if you blow an o ring all it would do it leak out crazy fast. I dont think tanks blow unless you are filling them on hot days. It happened in FLA a couple of years ago, i think. Anway, it is your decision as a parent as to when to start your kids in scuba. I dont have children myself but I know that if I did, I would only introduce it to them when they are ready to take the plunge.
I could have been an adult years before I was - I was an adult for years before I finally realized that I'd grown up! No two people are the same and some are ready for stuff a lot younger than others. In the end (hopefully), our parents know us better than we even do ourselves - we might not agree - but they are normally right (God it hurt me to write that!!!)
I only know how I have to bring up my own daughters - doing the best I can with what I know. For me to do less would do them a great injustice. For me to try to tell anyone else what to do would also be completely wrong. I'm only telling what I think for myself - and why. To put it rather bluntly I look at it like this: Are they ready for a sexual relationship? (that being something natural for everyone when they are mature enough) - if so, they MIGHT be ready for compressed air (that being unnatural for everyone - whatever maturity or age). I'm really not trying to preach here - just explaining how I think. Parents have the duty to work it out for themselves - and pray to God they get it right!!
