[edit] Move request
Correct spelling of the name (per several online articles/Rocky & Bullwinkle episode listings consulted [1]) seems to be "upsidaisium." Anthony Dean 05:00, 29 January 2006 (UTC)

The article currently says
- Manufacturing an aerogel filled with helium rather than air would create a lighter-than-air solid, but the helium would almost immediate leach out and the fun would be short-lived.
Wouldn't letting the helium leak out make it even lighter? The problem is keeping the air from leaking in, right? --DavidCary 08:11, 29 November 2005 (UTC)
[edit] Negative mass vs lighter-than-air
The article confuses:
- "negatively affected with gravity" (meaning an object with negative mass)
- lighter than air (meaning an object with positive mass, but less dense than air)
In both cases, the said object would "fall upwards" from the surface of the Earth, but for substantially different reasons. GregorB 22:00, 20 December 2005 (UTC)
