I created the sound effects with different methods through my iPad and Garageband. For the elevator noise, it was through Garageband and finding the right synth and key. For the chewing, I recorded myself chewing on chips because it would pick up better than popcorn. For the writing, I was scratching a pair of scissors against the inside of a food box. Lastly, to get the sound effect at the beginning of the sheet I hit a cotton shirt against my bed sheets while recording.
