Notes and Observations

• The goal is to create a yeast starter from the carrot peels for future carbonation projects.
• The mixture will be covered lightly and left for 24 hours, after which it will be fed daily.
• After 5 days, this was VERY active. Leaving it overnight, the popping sound from the jar hurt my eardrums.
