How to estimate it

Fermi’s official “Napkin math”

Picture the bowl after the bag is popped. How many handfuls would it take to empty it? Maybe 20. How many pieces in a handful? Grab one in your head. Maybe 20.

Handfuls in the bowl: ≈ 20
Pieces per handful: × 20
20 × 20: ≈ 400

Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.

Source calculation & reference

Hand count, one 3.2 oz Newman's Own bag (Chowhound, 2025): 437
Check: ≈ 65 g of corn × 5 to 7.5 kernels per gram (Purdue size classes): ≈ 330 to 490
≈: 440
