In this video I will be pouring molten aluminum into a seashell in an attempt to create a perfect casting of the internal structure. I started with a Marlin Spike seashell and made a simple sand mold. I then melted aluminum in my DIY home foundry and poured it inside the shell. I then broke the casting out of the shell and cleaned it up. This was a fun project and I may revisit this idea in the future.

    Would be cool with a resin casting around it with the shape of the outer shell, as if the shell had gone translucent and the void solid.
  • @danc101
    There are some fossils that are preserved in this way. The shell is filled with sediment and the shell itself is subsequently dissolved away, leaving a corkscrew shaped cast of the shell
  • @sebytro
    The aluminum cast of the inside part of the shell looks like a really cool drill bit. I didn't expect it to be so smooth and perfect. Nature is amazing.
  • @stabbrzmcgee825
    Yeah, I think it is worth mentioning that you really have to dry out the shell perfectly to avoid the vigorous interaction that aluminum has with water. Aluminum really wants to react with water. It isn't solely the steam expansion problem, as if that is not potentially hazardous enough.

    "My awesome wife put my channel's logo on my leather gloves, isn't it cool?" This statement is so wholesome and it brings me so much joy.
  • @TheMovieCreator
    The shell is mostly calcium carbonate, and when heated it turns into quick-lime. This does not only make it brittle, but can also change the volume a little. Handling quick-lime and water can be a bit risky since it dissolves to a fairly strong base capable of producing chemical burns, so neutralizing it with an acid like in the video is highly adviced.
  • @HawksNestYT
    The shell and the inside metal mold next to eachother are such a cool duo. Looks very mystic. Almost the king and queen of seashell people lmao
  • @tonywharton5220
    It's crazy to think that a living creature used to live in there. This is an amazing project.
  • @uigpoe
    ah yes, telekinesis; one of the most important tools in a makers arsenal. Savage would be proud
  • @AntoDesormeaux
    Hella cool! Looks beautiful. What huge shells btw I've never found one like that. PSA for everyone here: If you ever work with seashells, make sure you don't inhale any seashell shavings because mollusks incorporate toxic heavy metals into their shells :)
  • @namelesscrx
    The last part where you aligned the tip of the shell with the casting was so satisfying 😌
  • @genephipps6421
    The casting is quite literally a "Ghost in the Shell" as it is what the former occupant looked like. The thought gave me shivers.
  • @Laura-Kitty
    So cool! I'd love to see this with a variety of different shells. They would make a beautiful sculpture arranged together.
  • @RKOuttathebox
    The casting looks like the Golden Ratio in 3D. An amazing creation we live on and in!
  • @Aetila
    It looked even cooler when you attached the upper part of the shell, it became part organic, part metal, hehe. Excellent work there!
  • And that in palaeontology parlance is called a sock. It's the kind of "trace" fossil mould you get when the actual shell has dissolved away. Lovely idea!
  • @ericadler5749
    That’s awesome. I never would of thought of casting a shell. A+ on thinking outa the box and creativity. Thank you
  • Legit one of the coolest projects I've seen. Great idea and it came out so well. I didnt expect the shell to hold up and get the detail
