This sounds like a great project, but how hard it will
be depends a lot on what kind of method you use to simulate
the liquid.

Take a look at 

   Heating and Melting Deformable Models (From Goop to Glop)
   Authors: Demetri Terzopoulos, Platt, and Kurt Fleischer
  
http://www.cs.berkeley.edu/~job/Classes/ARiPBM/Papers/Terzopoulos-1989-HMD.pdf

   and

    Melting and Flowing
    Authors: M. Carlson, P. Mucha, R. Brooks, and G. Turk
    http://www.cs.berkeley.edu/~job/Classes/ARiPBM/Papers/Carlson-2002-MF.pdf

The first should not be that hard to do.  The second is a
nicer method but it is MUCH harder to implement.  Unless you 
already have a background in fluid simulation I suggest something based on the first.

OK

Big issue: how are you going to create the liquid?
