As more and more condensed material is added to the small drop that started to float the volume gets bigger and bigger, sometimes approaching 50 cc or more, but eventually the thin vapor layer separating the two is compromised and the floating "boule" merges quite rapidly <<<<< I would assume surface tension plays a big role. Are these gas laws? And, have researhers found a practical application?
