Leave it up to science to struggle to explain what has already been explained. Okay guys and gals here it is again: A. warm, water soaked soil, B. dry, cold(below 32 degree), still air, C. dead, vertical tick weed stems capable of wicking its interior strutted with warm, liquid water, D. and then under the pressure of warm expanding water on the interior and the cold air causing the exterior of the Tick Weed to contract, a rupture is created allowing the warm liquid to slowly ooze out into the cold, dry, still air creating Frost Flowers. Thank you very much and innocent until proven guilty. - Billy Joe Fudge
