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.

This is dumb as shit. Hot air balloons only go so high, less than 70k feet according to records. They only stay aloft if the heat is continually applied, if not, air cools and they sink. They move with the air, and the air moves with the planet.
This doesn’t work for the same reason jumping in an airplane doesn’t slam you into the back wall.
I don't think it was posted because it was brilliant…
70k ft: 21,336m
Sig figs!!
70k ft = 21 km
Ok but they're going really really high up
If you go much higher the balloon will leak heat through black body radiation faster than you'll be able to heat it. And even if you insulated the balloon in a way that didn't add too much weight you'd eventually get to the top of the atmosphere and hot air balloons won't go into space because they don't have any propulsion systems.
If you fill it with helium, it will go into space, and then it will immediately explode.
Balloons using hydrogen can reach 33 miles. But even then the atmosphere still moves with the ground.
Yeah, but anon smart, u dumb. Checkmate.
World view reaches 100k feet.
Isn’t that helium though?
