Short Film Marathon! Film #2

I recommend watching this film twice before answering the questions. It's only 2:30 minutes. 

Two Questions:

1. Why does the filmmaker increase the sound when the man is eating the Snickers candy bar? What does this symbolize in the film?
2. Why does the filmmaker have a distinct sound effect for every time the character puts his hand through the black hole? It's like the black hole has it's own sound effect. What's the purpose of this?

Please answer each question with a thoughtful response. Your answers don't have to be very long. However, you need to clearly state an idea or original thought in response to each question. Your response should be a few sentences at a bare minimum.
