That's an amazing device! What do you call such a thing (so I can find one myself!)?

We called them "Disco"
They are usually build using and old Plaughing Disc. You can have them from different diameters.
This one is pretty neat, but typical ones are smaller so that you can carry them around. You just need to set some wood burning and place them on top.
Here is a clear picture. You can weld it yourself. Nice DIY project for summer BBQ
You just need an old disc from a plaugh or planter. Any farmer shed is good for a treasure hunt...
