A thin-walled can collapses when the air inside is removed by a vacuum pump because the external air pressure acting on the outside of the can is greater than the pressure inside the can, causing it to buckle under the imbalance of forces. This results in the can being crushed as it is no longer able to withstand the pressure differential.
When air is removed from a balloon (by, for example, sucking the air out with a vacuum pump), the pressure inside the balloon becomes lower than the pressure outside the balloon. This causes the balloon to collapse as the higher pressure outside the balloon pushes in on the balloon's surface, causing it to shrink in size.
Assuming that outside the vacuum chamber there is some gas or liquid, then indeed there is a force that pushes on the walls to collapse. If it doesn't collapse, that means the walls are strong enough to withstand that force: weak walls would collapse.
When air inside a bottle is heated, it expands and increases pressure. If the bottle cannot withstand this increased pressure, it will collapse as the hot air cools down and contracts, creating a vacuum. The difference in pressure between the inside and outside of the bottle causes it to collapse.
Examples of vacuums include the vacuum inside a sealed jar, the vacuum of outer space, and the vacuum inside a vacuum cleaner.
The air is removed from the space between the two walls of a glass bottle to create a vacuum. This vacuum acts as an insulator, reducing heat transfer by conduction and convection, making the bottle more effective at maintaining the temperature of the contents inside.

If there were nothing inside the balloon - a vacuum - the balloon would quickly collapse due to the pressure of the atmosphere outside it. A firmer structure might resist the air pressure, but not a balloon.
When all the air is pumped out of a sealed can, the can's internal pressure decreases significantly, causing it to collapse or implode due to the unequal pressure between the inside and outside of the can.
The pressure inside the vacuum hose is lower than the pressure outside the hose. If the hose is old and weakened, it'll fold up on itself. If the pressure difference is bigger than the hose is expected to be able to deal with(by some other reason) the hose will collapse too. If someone has replaced a real vacuum hose with, say a fuel hose, that too can be a reason.
because vacuum will make the glass collapse

Liquids and gases expand inside a vacuum, so the organism's shape would be destroyed..
To demonstrate atmospheric pressure.
They don't. If such a vacuum collapse is even possible - which is not at all sure - the collapse could randomly start somewhere, and then expand either at the speed of light, or at a speed close to the speed of light.
