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.

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.
