Light but not "lighter-than-air." It doesn't float.

If the sample is lighter than air, why is it resting on the dandelion puff instead of floating away? Electrostatic attraction?

Great research work, though. Maybe the air there is especially light.

isn't aerogel already being used in super caps and marine refrigeration panels?

If you constructed a cylinder that could just contain the Eiffel Tower, the air in it would weigh more than the Tower.
