Is melting a chocolate bar an example of an igneous rock

I have a demonstration tomorrow for science and my topic is Igneous Rock. I have a chocolate bar that's hopefully going to be melted in a bowl, then showed to the class how it was reformed into something. My only concern is that it doesn't prove everything that an igneous rock may actually have, or if it's totally something different. I don't have much materials to use except for a chocolate bar, a bowl, and a microwave... So any tips or ideas that could help me? Thanks!

Sure, that works. It's better than the other kids who just put up power point slides.

You could show how after the chocolate melts it resolidifies into a new shape. Then get some sandpaper or some kind of fine grater and carve at it a bit to make some chocolate dust to show erosion, then collect the dust and pack it together tight to make "sedimentary" chocolate rocks.

It doesn't matter whether or not it's *exactly* analogous. The point is that you have a physical demonstration that gives the other students a picture to think about.

No, you've got it backwards. Melting a chocolate bar is NOT an example of an igneous rock.

Allowing melted chocolate to set into solid chocolate is an example of an igneous rock.
