I’ve always wanted to try to do something like this but I also have so many questions about the medium. Like is there a special sand/water ratio to get the best structure? Are there special tools you use to sculpt? What do you do about the extra sand you remove? It’s all so fascinating!
They also use a special kind of sand.
Oh really? Here I am thinking you just show up to a beach and go to town 😆
Nope. For those events, they actually bring river sand to the beach. Beach sand, like desert sand, is useless for sculpting - and for use in concrete, too. It simply is too round, while river sand is more ragged and edgy.
That’s also why those ultra-rich desert sheikdoms have to import sand for building their skyscapers, despite basically living in a big sandbox.
