I only have a few comments left.

1) I hope nobody gets hurt; the change to metal cannot come too quickly for me.

2) Again, do not assume that water and air pressures will behave the same in the same material.

3) MURPHY'S LAW. Also note that this is a case where nothing can go wrong, so invariably it will go wrong all at once when it does. Also read "The Wonderful One-Hoss Shay" by Oliver Wendell Holmes, Sr., a poem about something that was constructed with no weak points.

4) The cover also can't go on fast enough for me. Again, safety. Remember the fan covering debates we had this year?

5) Usually when a teenager is 100% positive about something, especially if it involves something dangerous, I head for somewhere safer.
