<human>:  What is the difference between skydiving and bungee jumping?
<bot>: The primary difference between skydiving and bungee jumping is that skydiving involves jumping from a higher altitude and free-falling through the air, while bungee jumping typically involves jumping from a lower scaffolding and bouncing back up on a bungee cord. Skydiving is typically done from airplanes or helicopters, whereas bungee jumping is traditionally done from platforms, bridges, or buildings. Additionally, skydiving requires the use of a parachute for a safe landing, whereas bungee jumping does not.
