Glue to mold caves with sand?

[Udeservit]

I would like to make my own caves but I need a safe glue to use. I would like to make the consistency of play doe/gritty sticky small rock to mold around balloon or suggestions for shaping?Also is there a search feature on the DIY thread page?i can't find it.


Glue recommendations that I can get at a hardware store?

You can use like an oven baked clay.
