I need to create a nest for a dinosaur egg cake for tomorrow. My idea is to glue pretzel sticks wogether with marshmallows somehow...can that work? Is there another good way to create a 3D piece that would look like a nest? Chow mein noodles crossed my mind....I don't think Rice Krispies will do it...Thanks, friends!!!!

you can dip pretzels in melted chocolate(but not too much) so they stick. do couple of layers, wait till it sets and do more layers. place a nest on a piece of parchement paper for easy removal

got a couple of more ideas, sorry im kind of slow today.
you can make a nest out of coconut shreds and chocolate mixture
or pipe chocolate over a upside-down bowl, cover is with parchement paper 1s. let it set, and take off the chocolate nest off the bowl: http://www.cakewhiz.com/cakewhiz/2011/04/default.aspx

My vote is for the chow mein noodles. My mom used to make birds nests for my class when I was a kid and that's what she used.

You could also use crushed shredded wheat-that looks nest-like.

Crushed Shredded wheat with melted chocolate would work well.

Thank you for all the great ideas!!! Couldn't find any chow mein noodles, but 4 year old had LOTS of pretzels, so we ended up using pretzels and melted chocolate. It was a huge hit - the kids at the party devoured the nest before the cake!!!!! Will try to post a pic in the galleries.
