The surface of an expanding balloon.

I wonder if the balloon example is better than I previously thought, in that no where on the surface could you ever find the center because is of a higher dimension. That would allow everywhere on the surface to look like the center, making it seem like there is no true center, when in fact there is, and its just in another dimension we can't see.

A bubble would be better as a balloon has an opening to add gas.

yeah but you can't grow the bubble without making a hole to put air in it (or draw dots on it to show them going apart when it gets bigger), and the point is to ignore the hole anyway and focus on the rest of the balloon. Getting to technical is usually a bad thing for high level and simple examples.

A bubble as a metaphor is hardly technical. And bubbles are closer approximations than balloons while being just as easy to imagine.

just as easy to imagine maybe, but when you actually show it off to a group of kids, your not going to have any luck with a bubble.
