Think of the air around us as a huge ocean of air that sits ontop of the land. Air has weight...incredible weight. If you take the air out of something, the there is a vacuum inside it and nothing to support it and the air pressure crushes it
Yes
Steel.
idkk... -_-
yes it's true
It means that the air pressure that sealed the can - can not be removed

1. Steel cans arrive at a recycling center. 2. The cans are removed from the conveyor belt with an electromagnet. 3. The cans are smashed and baled. 4. The steel cans are delivered to a facility where they are melted and cast into ingots. 5. The steel ingots are rolled out into sheets. 6. These sheets are delivered to manufacturers that turn them into new cans.

according to the TSA policy, no aerosol cans are allowed. It doesn't specifically say airhorns but it should be implied. i.e. spray cans, lighter fluid cans, hair spray cans.

If both bags are the same size, there would be more cans in the crushed can bag and it would weigh 3 or 4 times more than the bag without any crushed cans. If there are the same number of cans in each bag, as long as the cans were not closed, they would weight the same. If the cans were sealed, the air inside would add to the weight of the bag. as the uncrushed cans would leave a lot of air in the bag that would be lighter so a bag of crushed would weigh more as there would be more cans in there
Gas stations that have a store usually sell compressed air cans for customers and some simple garages may have their preferred brand of compressed air for sale out of their own stock if you ask.
