Imposter! No Murcan would use "rubbish bin".

Piss off. You're not even an American. Don't tell us what to do with our FBI.

One of the things I read said it has to be at least 93% to make balloons float.

Oh. I had that totally bass akward.

No helium found on earth ever, was pure enough for cryo. Not even close. All helium is found in low concentrations and spun extracted to concentrate and start to purify it. Then there are additional filter methods to finish concentrating it. Removing the hydrogen is about the hardest because it's also abundant and small and light.

But helium used in balloons can absolutely be concentrated and purified.

Balloon helium is 3% helium. So every 33 balloons is one Balloon worth of pure helium. No helium starts off pure. It all gets concentrated/separated to get that way. "Balloon grade" helium can be concentrated just fine and considering that thousands of those balloons are filled every day, it is a lot of wasted helium.

*I had my percentage swapped, it seems. Balloon helium is 97% helium.

It's a nail in the coffin to know the world wide webs golden age won't have a resurgence and that you'll no longer be able to believe or trust anything you watch, read, or hear, pretty soon.

Don't underestimate the ability of someone selling denim jackets with white t-shirt sleeves sewn into them.

I guess nobody much tried to see if it was fake or not because it was mundane enough to not matter and believable enough because there was a million people like this guy smoking in McDonald's in the 80's. My great grandma was a chain smoker. Literally all the time. I remembe going to McDonald's for lunch in the 80's and sitting there eating while she chews and smokes at the same time.

So there was no reason to suspect or care about it being a real pic.

These motors have been a knows issue in refrigeration for a long time now. A lot longer than just 3 or 4 years. Meanwhile I have a 15 year old fridge/freezer still going great and a full size upright deep freeze in the garage that's like 30 years old.
