What happens if you fill a seashell with metal? Huge conch shell filled with molten metal

In this video I will be filling a huge seashell with molten brass in an attempt to create a perfect casting of the internal structure. I started with a Spider Conch seashell and made a simple sand mold using petrobond casting sand. I then melted brass in my DIY home foundry and poured it inside the shell. I then broke the casting out of the shell and cleaned it up. I rearticulated the parts of the shell onto the casting and then mounted the whole thing on a piece of Mahogany wood. This was a fun project and I may revisit this idea in the future.
