Elephants and other weightless topics

I’m a librarian, and today I was asked this reference question:

What is as big as an elephant but doesn’t weigh an ounce?

Ruling out the obvious jokey answers, like “an elephant, because it weighs more than an ounce,” or something like that.

Any ideas? Roomful of hot air? Giant bubble? Helium inside a hot air balloon?

An elephant in orbit.

How about an elephant-sized hole? An elephant’s shadow? I think that if we’re going to rule out the “not exactly an ounce”, then the question means that the thing doesn’t weigh anything, unlike a cloud of gas, which would weigh some small amount.

By the way, if you want to change your name to just “kelebrian” without the full e-mail address, or to something else entirely, you can drop an e-mail to one of our administrators, Lynn Bodoni or TubaDiva, and they’ll take care of it for you.

Mother of 3 here. It’s a riddle [sigh].
