This is the hidden punchline to the war on liquids:
The government is incapable of testing for high concentrations of the one substance they claimed was dangerous as a liquid. Peroxides are everywhere, detergents and cleaners, toothpaste, medicines, honey, so it is likely many people would show traces of it on their bodies. So the feds solution is to simply ban all liquids in perpetuity.

So, you are saying what it says on a label is always what's in a bottle?

... As rocket fuel, the hydrogen peroxide is at a high concentration, is highly explosive and needs a large, complicated chemical plant to manage it. It is highly unstable.
As a cleaner, bleach, it is highly diluted. It is mildly corrosive, so if you do end up being in contact with it, you need to wash it off with water. It is non-explosive, stable and can be stored in pretty much anything (plastic bottles for example). It isn't dangerous.

Hydrogen peroxide is also used in the "jet pack" device.
... It's major disadvantage is that there are many catalysts, and your container full might just spontaneously degrade into steam.
The way to avoid this is to dilute the hydrogen peroxide with water. But a safe-to-handle-unsealed concentration is pretty much useless as a precursor for making (more) dangerous compounds.

So yeah, in this case if it says "3%" I believe it's not 90%. But then, I'm one of the spicious people who dun good in math at skool.

But I have to say, if TSA had to declare war on an entire state of matter, it would have been worse to suspect all solids or all gases.
(Could mention plasmas or Bose-Einstein condensates but I won't.

I am from Kentucky and for me that is the only state that matters. Well, the others matter, just not as much. (And, what do my big TV and headphones have to do with anything?)

Just wait a couple of weeks and the TSA will post holiday travelling tips. It will say that pies are allowed. I'm not a cooking expert but I assume that a pie contains far more than 3 oz or liquid or gel. It's just another inconsistency with the liquid ban.

To be fair, you'd be talking about exposure to a rocket full of hydrazine--at which point you've definitely got several things to worry about.

Actually, just small monoprop or biprop spacecraft thrusters will do the trick. The biprop thrusters have the added excitement of N2O4 as the oxidizer. One whiff tends to oxidize one's ling tissue quite efficiently and completely.

Re-read posts # 3 and #8. Take your time. Here are the key bits underlined for you.
Summary: 90% hydrogen peroxide in a plastic bottle labelled "Clear Care 3% H2O2" is so unstable and corrosive that it won't be in the plastic bottle long enough to go through security. Hydrogen peroxide mild enough and stable enough to last the ride to the airport and the security queue is so diluted with water as to be useless as an explosive.
So yeah, in this case if it says "3%" I believe it's not 90%. But then, I'm one of the spicious people who dun good in math at skool.

Hydrogen peroxide
Here's AskTSA telling a pax he can bring hydrogen peroxide in his carry-on:

Has TSA changed to rules on H2O2?

Insert obligatory "the rules are whatever the TSO on duty say they are" rant.
Now, with all of that out of the way ...
... I note that searching for hydrogen peroxide on the "Can I Bring" tool on the TSA website brings up the standard advice on liquids.

Hydrogen peroxide and the TSA
AskTSA told someone several days ago that he could take hydrogen peroxide, 30% 1/2 cup for a science experiment, in his carry-on. (written instructions for this experiment say 6% H2O2)
The question has been asked twice on the TSA blog if their rules about hydrogen peroxide have changed but, of course, <deleted> hasn't bothered to respond.
My question is: can anyone say affirmatively that TSA now allows H2O2 or was this just another egregious mistake by AskTSA?
