Les courants violents peuvent engendrer un deuxième type d'échappement, l'arrachement ou l'entraînement de gouttelettes. Dans ce cas, un bourrelet se constitue à la marge distale de la nappe retenue par la barrière; le courant déstabilise le bourrelet duquel il arrache et entraîne des gouttelettes. Si ces dernières ne sont pas suffisamment légères pour remonter sous la nappe, elles s'échappent sous la barrière. 2, record 1, French, - arrachement%20de%20gouttelettes
