A water droplet impacting a super‐hydrophobic graphene foam surface spreads into a pancake shape, then retracts and fully rebounds off the surface. In spite of its microporous structure there is no indication of any significant droplet pinning or penetration into the graphene foam during the droplet impact. Such superhydrophobic graphene foams, as described by H.‐M. Cheng, N. Koratkar, and co‐workers on page 75 , show potential in a variety of applications ranging from anti‐sticking and self‐cleaning to anti‐corrosion and low‐friction coatings.
