This study develops a controlled generation of multiple droplets simultaneously to examine the physics of multiple droplet impacts on a solid surface. The developed droplet generator consists of a micro-controlled syringe pump connected with two needles. The control of the speed and steps of the motor of the syringe pump allows precise simultaneous ejection of a single droplet from each needle on demand. The droplet impacts on a solid substrate can lead to the interaction of the spreading lamellas between droplets to form an uprising liquid sheet. Simultaneous high-speed imaging from two views (front and side) of the sheet temporal evolution for three impact Weber numbers (We) of 55, 84, and 128 reveals the three-dimensional features, including the semicircular shape, instabilities, cusp formation and finger formation, of the sheet. The dependence of the height and periphery of the sheet on the impact Weber number is presented.
