1,000
sprays
How to estimate it
Fermi’s official “Napkin math”
Start with the bottle, 100 ml. How much comes out in one spray? Just a fine mist, maybe a couple of drops. A drop is tiny, call it 20 to a milliliter.
- Bottle
- 100 ml
- Drops per ml
- × 20
- Drops per spray
- ÷ 2
- 100 × 20 ÷ 2
- ≈ 1,000 sprays
The bottle is 3.4 fl oz, and an ounce is 6 teaspoons, so about 20 teaspoons. How much is one spray? Just a mist, maybe a couple of drops. A teaspoon holds about 100 drops.
- Bottle
- 3.4 fl oz
- 6 teaspoons per ounce
- ≈ 20 tsp
- Drops per teaspoon
- × 100
- 2,000 drops ÷ 2 per spray
- ≈ 1,000 sprays
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
Source calculation & reference
- Bottle
- 100 ml
- Fine fragrance pump dose (Aptar makes 70, 100 or 130 µl)
- ≈ 0.1 ml per spray
- 100 ÷ 0.1
- ≈ 1,000 sprays
Reference cited by Fermi: Aptar Beauty fragrance pump specs (70, 100 or 130 µl per spray) and the Basenotes rule of thumb of about 10 sprays per ml
