This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

Anon is often crazy.
Anon is often depressed.
Anon frequently shares thoughts that are immature, offensive, or incomprehensible.

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

The density of the air becomes so thin that I don't think you could have a container for enough hot air that wouldn't weigh more than the lift provided. Helium weather balloons end up getting so large because of the pressure difference that they end up bursting at those altitudes.
