Episode notes
Let Food Rest After Microwaving
- Let microwaved food stand after cooking so heat redistributes from hot spots into cooler areas.
- Reheat again briefly if needed to ensure even temperature throughout the dish.
Microwave Heating Is Non‑Ionizing
- Microwaves use non-ionizing radiation that jiggles water molecules rather than breaking chemical bonds.
- This means microwaves heat efficiently and do not cause DNA-damaging ionization like X-rays do.
Size And Water Matter For Microwave Effects
- Very small, dry creatures like ants absorb negligible microwave energy and can avoid hot spots by moving inside the cavity.
- Size and moisture content determine how strongly microwaves heat an object, not mystical effects.
