Sea urchins on the rims of your tires
This might be the ‘coolest’ rim in the town where this photograph was captured. The frozen water looks like a spiky sea urchin that can easily pop the tires of any other car if they get too close. This little hidden weapon can be unlocked by driving your car quite fast in regions where temperatures are freezing when there is water on your car’s tires.
Two factors account for this phenomenon. One is the water freezing from low temperature, and the second is the centrifugal force pushing water droplets outwards, making these spikes just like the stings of a sea urchin.
