Reversible gelling and ungelling of oil

Reversible gelling and ungelling of oil.
Research of Hee-Young Lee, Seung-Won Ko and Kevin Diehn (2009)

This movie shows how we can convert a liquid oil, such as kerosene, into a gel, and then convert the gelled oil back to a liquid. In the movie, a gelling agent is squirted onto liquid oil and in a few minutes, the oil spontaneously gets gelled. Thereafter, an ungelling agent (ethanol) is added to the gelled oil, whereupon it is transformed back to its initial liquid state. The science behind this behavior is discussed in our Langmuir (2010) paper.
