Built this after watching Black Magic Craft make one out of Foam. I haven't made one yet so pleas tell me how it goes. you will need fairy lights. I suggest to use some sort of clear epoxy to disperse the light a bit more. Pleas tell me how it goes.
I made this in blender and added the .blend files incase you want to edit my design. also I left a blank lid for you to create your own symbols.
