Why static cling is worse in dry air
Dry air lets charge stay on cloth, because there is no moist film to leak it away.

From the opening
Static cling is worse in dry air because electric charge stays on the fabric instead of leaking off. Contact and separation put the charge there, and dryness is what lets it remain long enough for two layers to pull together. The opening covers how contact leaves opposite charges, why a water film lets charge leak, and why heated winter rooms are dry.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
