I'm an artist attempting to make a sculpture out of a lava lamp by inserting small sculpted or painted objects inside. I'm hoping someone might know before I take it apart if it's possible to insert small porcelain objects, pieces of acetate, or any other material inside the lamp that might float without just sinking to the bottom, floating to the top, or melting? Thanks for your response.
