Foam sweet foam.
Residents of Footdee, a fishing area in Aberdeen, Scotland, were shocked to wake up Tuesday morning to find sea foam covering their homes, streets and cars, the BBC reports.
The frothy stuff was carried onto land by strong winds off the North Sea, and left the small fishing village (known to locals as "Fittie") looking as if it had been hit by a snowstorm.
"I woke up at 7 a.m. and I couldn't believe it when I looked out the window to see how bad it was," resident and artist Joyce Cairns told STV-TV.
"At first I thought it was just the sea coming over, but the foam gradually came closer and closer to the house ever 15 minutes."
Sea foam is produced by salt water getting churned up with various organic material. It is generally not hazardous to humans, though there are some exceptions, such as when harmful algal blooms decay near shore and subsequently become mixed up in the foam.
