Another canister question

[mitchy]

Haven't been out yet this year, so I can't test this theory...

Can an aluminum water bottle be converted into a canister for a light?

Would it have the integrity to not collapse under the water pressure.

I understand that the lid would have to be modified/a new one with latches manufactured.

Take one for a dive, and find out!

Now that's thinking aoutside the box! The "duct tape and bailing wire box"... lol
I bet the vessel is fine, the lid may not.

I went on a chamber ride with a group a couple of years ago. My son took his aluminum water bottle into the chamber and forgot to crack open the lid. It was only partially full and at about 130ft there was a loud bang and the bottle collapsed.

We have the answer! Thanks for sharing...

why couldn't you use a nalgene bottle, I can say they wouldn't collapse.

Have you had one underwater before? While empty?


I have a few old Nalgene bottles I'll have to test. Now I'm curious.

I have not, BUT I know that they were made from lexan.

Any potential worries of heat buildup or chemical mixing with the nalgene?

I don't know that there would be an issue, I've used my nalgene with coffee with no ill effects. It would seem to me that you would have to have enough wire to pre-twist it when screwing down the lid. I'm pretty sure that the box style battery holders are made from lexan as well.
