Vitality Air

Canadian company which started out as a joke bottling Rocky Mountains air has seen its product fly off the shelves in pollution-hit China, with first shipment selling out in four days.

A Canadian start-up company bottling fresh air from the Rocky Mountains has seen sales to China soar because of rising pollution levels.

Vitality Air was founded last year in the western Canadian city of Edmonton but began selling in China less than two months ago.

“Our first shipment of 500 bottles of fresh air were sold in four days,” co-founder Moses Lam says in a telephone interview with the Telegraph.

A crate containing 4,000 more bottles is making its way to China, but he says most of that shipment has been bought.

A 7.7 Litre can of crisp air taken from Banff National Park in the majestic Rocky Mountains range sells for roughly 100 yuan ($15.47), which is 50 times more expensive than a bottle of mineral water in China.

Vitality Air’s biggest challenge is to keep up with demand because each bottle of fresh air is filled by hand.

Maybe those in China could use this idea with maybe a few more filters added considering the intake will be extremely polluted air.

Maybe they could "Can" their own and save a few bucks.

How to make Hardtack

Hardtack is an inexpensive and long lasting way of sustenance, in the absence of perishable food. How to make Hardtack, as another use of flour on a survival scenario.
...............
Hardtack is a hard cracker-like biscuit made of flour, salt and water, was one of the most typical rations issued to soldiers and sailors by the U. S. government because it was fairly nutritious and unlikely to spoil. Hardtack’s use as a military ration can theoretically be traced back to Roman times, but the first widespread usage by American soldiers was during the Civil War...

After the Civil War, this hard bread continued to be a staple of the soldier’s diet and was made in government bakeries located in eastern cities. Shipped in barrels to the troops in the west, Hardtack had to be tough. This toughness made Hardtack ideal for campaigns and patrols away from the post or fort.Normal breads were too delicate to survive the long trips west and would spoil very quickly. Hardtack was extremely hard and was called "teeth-dullers," "digestible leather&,quot; "angel cakes,” and “ammo reserves" by those who ate the hard bread. Some Hardtack was so hard it had to be broken with a rifle butt or a "blow of the fist" to prepare for eating. Soldiers normally softened the pieces by soaking them in coffee, frying them in bacon grease or salt pork fat, or crumbling them in soup.

The Question arises constantly as to the correct recipe for hardtack. Here it is: Flour - Water - and a little salt. Mix together to obtain an elastic, but not sticky dough, Roll to inch thickness, bake in 400 degree oven until slightly brown.Allow to cool (may still be somewhat soft). Put in 200 degree oven until hard. Prick with nail or sharp instrument.

NO BAKING POWDER, SODA, SUGAR, CINNAMON, RAISINS OR ANYTHING ELSE!!

(C rations contain a form of hardtac in the shape of a cracker. You can make your own. Hardtac from the civil war still exists but I am not sure if its edible.

Hardtac lasts very long when its prepared correctly. I think it is a very good choice for a survival food. Bake some and be prepared.)

(Honey also keeps for a very long time. Stock up on honey also. I think one could survive on honey and hardtac for a long time even if they didn't eat much else.)
