The snow sat on the car for roughly 36 hours and the ice crystals bonded. The sun came out briefly and warmed it enough the “blanket” started sliding. The cohesive unit got caught on the license plate and started folding on itself. It was really cool to see, no pun intended. It is relatively rare for all the right components, temperature, water content of the snow and the slope of the car for this magic to happen.
