abstract  ="How does the impact of a deformable droplet on a granular bed differ from that caused by a solid impactor of similar size and density? Here{,} we experimentally study this question and focus on the effect of intruder deformability on the crater shape. For comparable impact energies{,} we show that the crater diameter is larger for droplets than for solid intruders but that the impact of the latter results in deeper craters. Interestingly{,} for initially dense beds of packing fractions larger than 0.58{,} we find that the resultant excavated crater volume is independent of the intruder deformability{,} suggesting an impactor-independent dissipation mechanism within the sand for these dense beds."}
