Taylor instability is investigated in a series of experimental runs at an Atwood number of 0.095 (density ratio of 1.22). The fluids used are octyl alcohol and water. The expected bubble and spike formation is observed, and, for the first time, the spike is seen to flatten and curl over due to Kelvin‐Helmholtz instability. The results are compared with the analytical, numerical, and empirical findings of others.
