Last year, there was a marshmallow arch challenge. This year, Marshmallow Madness Returns.
Your materials: a bag of large marshmallows, a box of toothpicks, 2 pairs of tongs.
Your challenge: build the tallest marshmallow arch you can using the materials above, but you may not touch the marshmallows with anything but the tongs.
Good luck! Photo, video, animoto submissions all accepted!
