[Dragon Ball]How Do Capsules Work?

They seem to be able to store anything from swords to motorcycles to small houses. Is there a size limit? What happens to what's inside? What would a person experience if they were in something that got capsulized? How well do living things deal with them, such as a plant in Kame house?

In the Dragon Ball universe, access to other dimensions is fairly trivial technology. The hyperbolic time chamber, for example, is a particular example of transdimentional travel. 

All Capsule Corp vehicles and structures are stored in temporary pocket dimensions, which are accessible through the capsule. Placing something inside a pocket dimension is very energy intensive - requirements increase proportional to the cube of their mass. While there is no hard cap on how much mass can be capsulized, it becomes prohibitively expensive quite quickly. 

These dimensions can be created with variable properties. All universal constants need to be defined. It would be possible, for example, to create a universe where the strong force did not exist. Anything sent there would immediately unravel at the subatomic level. Assuming the pocket universe has properties identical to our own, and assuming a person could transport their own atmosphere (ie space suit), they a human can be capsulized.
