Episode notes
Ice Creates Nucleation For Fizz
- Fizzy drinks contain dissolved gas that forms visible bubbles at nucleation sites.
- An ice cube provides a large nucleation site so gas molecules gather and fizz more rapidly.
Stainless Steel May Bind Sulfur Smells
- The garlic/onion smell comes from sulfur-containing compounds on your skin.
- Melissa suggests stainless steel may bind those sulfur molecules and water helps move them to the metal.
Wait Before Repeated Recommendation Emails
- Do not email professors multiple times within days when requesting recommendation letters.
- Wait at least one to two weeks before a polite follow-up so you don't bury your request in their inbox.
