Ha! Look at the price on those Wheat Thins. I personally never pay more than $15 for them. Suckers!
Admin
I always wonder why people are insistent that magnetic and infrared fields everywhere can be everything but bad for them?!
Frist! (well... secnod).
Admin
I'd expect $400 for shipping from an eBay auction, but not Amazon.
Admin
That bear is nothing. I have one that protects me from tainted orgone, WiFi radiation, and underpants gnomes.
Captcha: pseudoscientific bullsh!t

Yawn. Anyone who's ever used Amazon's system to publish their product data knows that what's shown here is a minor glitch. I've seen entire storefronts have 100% sales on every item and allow checkouts to occur.

That helium bubble wrap idea is ingenious.
Admin
Amazon's Sellercentral may as well be ebay - it's subject to a comparable amount of oversight.
While I'm sure most of these are user error, their "Amazon Desktop" application is buggy as hell.

The earth's magnetic field is 30-60 microteslas. That's pretty weak; a modern high-strength neodymium magnet is about 1 tesla.
Admin
Looks like the Advantus Neon Open Sign is all that, and a bag of chips.
(2003 anyone?)

I bet that bear will sit nicely on their stack of favorite VHS tapes.
Admin
Dude, where do you get them for $15?! They are AT LEAST $25 here. :-/
Admin
Wait till you see Hydrogen bubble wraps.
"OMG! bubble wrap!.. ... ... POW!! blood springling everywhere
Admin
Admin
Yeah, so whats up with that? Why use a measuring system that counts in a different base than your usual counting system. Either count and measure in 10 or do it it something else, no?
Damn tradition...
Admin
If by "used" you mean "used to the exclusion of all other systems," you are incorrect. We use the metric system for a number of things here in the United States.
If by "used" you mean "used, possibly in addition to other systems," you are incorrect. Liberia and Myanmar also do not use the metric system officially.
Admin
I was just wondering about that. Can helium be produced cheaply enough to save enough energy to make it worth it?
Admin
No-one has noticed those "tin wheats" are actually a advantus open sign?
Admin
No. In fact helium is a finite resource, because the tiny molecules are slowly escaping from the Earths gravity and drifting off into space. It is globally believed that we may have only about a century or so of helium left. After it is gone, there will be no more.
Admin
You might be able to get enough helium in something like mylar in a packing container to make a small dent in the weight, but many (most? all?) shippers also charge you for size.
But wait! Here's an idea! You could compress the helium, so that it doesn't take up as much space! (Yes, I am joking. I leave the physics of why that's a bad idea as an exercise for the reader)
Admin
So really, we in the US are in good company!
Admin
Liberia and Myanmar -- true paragons of technological and economic innovation.
Admin
Quick! Call Al Gore! He'll know what to do ...
Admin
As a computer geek I prefer my measuring systems to use base 2. 1 Gallon = 100 Quarts = 1000 Pints = 10000 Cups.
Admin
Admin
That's great and all, but I think you're forgetting about a certain airship and why we don't use hydrogen anymore.
Admin
Well, if ya just fuse some hydrogen together you'll get helium in return plus lots of energy to fuse more hydrogen together. A few dozen thermonukular devices should be more than enuff to replace all that leaking helium!
Admin
I've become used to see over $100 prices for overseas shipping... But $400 is still too much.
1 tesla!!! Are you sure about that? It seems too much for me.
Admin
The molecular mass of hydrogen is half of the atomic mass of helium (take another look at the periodic table). So, its density is half of that of helium.
Admin
YOU KNOW THAT THE PRODUCT MUST BE LEGIT IF THE TEXT IS IN ALL CAPS.
Admin
Not strictly true, as there's always a little coming off Uranium 238 and other isotopes that decay by alpha emission.
Admin
Is a tank of helium heavier empty or full?
Admin
You most likely know it as Myanmar, but it will always be Burma to me.
Admin

Admin
I have a great idea: vacuum bubblewrap. It weighs even less than the helium and hydrogen stuff!
Admin
Oh! the humanity...
Admin
Actually, hydrogen has one proton and helium has two. The protons make the element. Neutrons can be added to change the isotope.
Hydrogen a few useful isotopes, which have more or less neutrons. Deuterium (2n) is nuclear fusion fuel in the Sun. Tritium (3n) help U.S. nuclear warheads get extra bang (I'm not sure how).
Admin
As for H-bombs, I think they use lithium deuteride, which is solid and non-radioactive. Tritium is produced temporarily during detonation.
Admin
Heavier full. The sealed metal tank displaces the same amount of air in both cases, so it's just as buoyant in terms of displacement.
As the mass of the compressed helium is likely greater than that of the uncompressed air, it will be heavier when full.
Captcha: Gotcha
Admin
But the amount of Deuterium and Tritium in a sample of Hydrogen is vanishingly small (unless it has been specifically isolated), the same with the amount of Helium 3. So hydrogen gas is going to be very close to half as dense as helium gas (according to the Ideal Gas law, which should apply well enough to Hydrogen and Helium at atmospheric temperatures and pressures)
Admin
Final paragraph = Best post I've seen in a long time.
Admin
Brilliant! There's no shortage of vacuum either. Just a couple hundred miles up there's enough for everyone. (Non USA folk should feel free to use more familiar units, including but not limited to hands, cubits, parsecs and wavelengths of Cesium light.)
Admin
For those who are well-versed in neither magnetic, nor infrared therapy, I am pleased to provide the following version of the ad in layman's terms:

I could not agree more strongly. Still...
What time is it?
Oh right, 1185260400.
Admin
It's not a totally crazy idea. If you can get a structure strong enough to contain a vacuum without collapsing, yet light enough so the total volume displaces enough air - then you have an airship. In fact, it may be easier to do on a smaller scale, what with nanotechnology and all, so vacuum bubblewrap may be feasible.
Damn, I have said too much - races to patent office
