What's Inside A Double Wall Drink Bottle?

Cutting open a double-walled stainless steel drink bottle.

Vacuum design with reflective silver on both inner surfaces drastically improves insulating properties!

[@greenspiraldragon]

The really good ones have a vacuum inside of them which insulates better than an air gap.

ok , this is a start for knowing the design of a non-vacuum dbl-wall bottle. good demo

[@stuartlarge6296]

Was curious about it ..... searched it....... now I know......
Thanks

Vid Didn't show the important part. !
Inside the bottom.

[@NatMart9394]

Wondering Why mine now looses its heat very quickly ?
Must have bridged the air gap somehow.

Good video but the double wall gave it a way

How to repair?

[@lemkeinbiz]

You could have done a cutaway so we didn't have to watch you struggle through cutting through that

[@SuperAndyyyy]

the sound was unbearable

[@toddspires603]

How to fix heat loses ?

[@Aaron_Barrett]

Is it vacuum inside or just air?

[@kiwihexbug964]

This one was a cheap bottle, so it was just air between the two walls.

[@dolores3662]

Company names that make these?

[@GeorgeGalanisJ]

One well known is Chilly's

[@devorahlipschitz2963]

How does it work?

[@prdoohan]

There is a vacuum drawn between the two layers during manufacturing, so there is no air to transfer heat between the two surfaces.
