- •
Impacts of droplets, depositing from gas core, are studied experimentally.
- •
Two types of film perturbation due to impacts - craters and furrows - are observed.
- •
Furrows mostly occur on the base film, craters occur on disturbance waves.
- •
Crater impacts create secondary droplets, furrows create bubbles in liquid film.
- •
A droplet may survive the impact, being partially broken into smaller droplets.
