Ei au filmat cu încetinitorul o picătură de apă care cade pe nisip. Picătura ţine în acest experiment locul asteroidului, iar stratul de nisip este suprafaţa Terrei.
La impact, suprafaţa granulată se deformează formând un crater. Interesant este că prin căderea unui strop de lichid se reproduce aceeaşi morfologie a craterului ca în cazul unui impact real cu un asteroid, spun cercetătorii.
Clipul a câştigat anul acesta premiul Fluid Motion decernat de American Physical Society.
