Can Water Float on Oil? Chi M. Phan,* Benjamin Allen, Luke B. Peter, Thu N. Le, and Moses O. Tade 201228104609461310.1021/la204820a Equations 3−5 in the original paper were wrongly written because of changes in notation during manuscript preparation. These mistakes do not affect the modeling results. The equations are corrected as follows: γwa cos θ1 + γow cos θ2 − γoa cos θ3 = 0
