Creating Glaciers

[Afrancis]

Hi i just came across your post, and i wanted to know how i can use this effect to make a melting object made from ice? Take for example a bottle how can i make it look like its melting? i am working on a project where i have made moulds of objects and filled with water to make ice. I then remove the mould and film it melting, however i can only do this with small objects and i want to make a mould of something like a laptop but as i am only a student i cannot afford to have some ice sculpture made.
