Using high-speed cameras, MIT researchers observed that when a raindrop hits a surface, it traps tiny air bubbles at the point of contact. As in a glass of champagne, the bubbles then shoot upward, ultimately bursting from the drop in a fizz of aerosols.

These aerosols may be released during light or moderate rainfall, and then spread via gusts of wind. • Video produced and edited by Melanie Gonick/MIT • High-speed droplet footage by Youngsoo Joung • Rain falling and bubbles in glass footage: Pond5.com • Music sampled from Running Waters by Jason Shaw • http://freemusicarchive.org/music/Jas... • http://creativecommons.org/licenses/b...
