Let's make a sandwich with the earth as "spread". I'm exactly on the other side of the planet (for the Belgian crowd) so we got an unique opportunity to make a giant sandwich. I placed my loaf of bread in Centennial park in Sydney and uploaded the photo to this map. If you do the same we'll have an Earth Sandwich!!!!

Start making your own sandwich!
