Title pretty much sums it up. Thought about trying to plug it up and force air into it. Any ideas?
 
Seems like that would work... Just put a stopper in the top and try to fill the better bottle with air from a air compressor..

:mug:
 
WHOA, easy with the air compressor thing. That's a lot of air in something not meant for pressure. Ever see a tire blowout? You could get really hurt. Partially fill with some water before doing anything crazy. Water doesn't compress! Play it safe and use a stick, live with it or buy another one!
 
If you fill it with hot water and then cork it, it will force the water to expand and create a higher pressure and will probably fix the dent, assuming it's not on a crease.

Water contracts when it cools (until it's cool enough to crystallise, whereupon it expands); filling it with hot water and corking it will produce a lower pressure, not a higher one.

Yes and no.

When the hot water gets into the tank it will still be vaporizing. If the water vapor has nowhere to escape since you capped it and it is an expanding gas it will increase the pressure. Once the gas cools (which will take a bit) then it will condense back to liquid form.

Maybe if it's boiling, but empirical testing with (as originally specified) hot water fails to show a significant increase in pressure.
 
Huh?

I didn't pour it into a vacuum. I poured it into a PET container with an airtight closure and a minor dent.

empirical, adj. Derived from experiment and observation.

Who are you to trifle with natural selection?;)
 
I'd try the ping pong ball technique...
Every time my dog would crush and dent a ping pong ball, I'd just pour boiling water over the ball, causing the air inside to heat and expand and pop the ball into its original shape.

Instead of putting hot water inside the better bottle, just try sealing it with only air and pour boiling water one top.

I guess a dented BB is much better than a broken glass carboy :)

Mythbusters did an episode where they pressure tested standard 5gal water bottles and they held 95 psi. I would guess a better bottle could do the same, so if you stay under 30 or so it should be doable.

Either way though, I would rig something and have it at the end of a 50' air hose. If it works your better bottle is fixed. If it doesn't you have a $25 firecracker.
 
If the dent is near the botton, just use a broomstick. If you want to try pressure, put about 1 gallon of very hot tap water in, put a water cooler cap on it, hold it on tight and shake.
 
Notice the use of TAP WATER. Not boiling water or water heated on the stove. You will melt your Better Bottle if you do that.

The Better Bottle is rated for water temps up to 140 degrees Fahrenheit.
 
Fill it with water to about 4 inches from the top.

Open your hand and smack the top of the opening really hard with your palm. The pressure sould force the dent out. If you do this to a partially filled bottle you'll break the bottom out...should work with plastic...;)
 
I think the manufacture has advised that dented BBs are no longer oxygen barriers at the crease point.
 
Water + Dry Ice + Cork

You'll just have to hope the cork is weaker than the sides, or there will be one heck of a boom.

This would be best suited when with some friends and after a few homebrews. If it can't live to see another brew, it midas well go out with a bang!

Seriously though, I think filling it with water and freezing. That should create more of an even pressure.

You'd be suprised, this should work well. I was going to say about vinegar or lemon juice plus baking soda and cap it to apply low pressure to pop the dent, but I totally didn't think of homebrewer_99s' suggestion!
 
Just use some air from the compressor. You won't have it sealed so well that you could explode it. But, if you do, send videos.

You may be a chem major, but you obviously didn't take any physics. Leave a half full water bottle in a hot car... as water temp increases, the bottle will firm up.

If you put hot water in and then cork it, it will lower internal air pressure and force the container to contract more.

You have it backwards.
