Hank saw that he was no where in particular. Floating in space.
First Hank panics because he remembered all the lessons he took on space and how it's a vacuum, but then be realised that he was still alive and well.
He moved carefully and found that if he moved like he was swimming he could move forward and control the speed. He began to spin around and laughing but the next thing he knew he was spinning quicker and quicker until he understood what the fruit in his morning smoothies felt like when he blended them.
He came to a sudden stop when he landed on the surface of something very hard.
