Madeline's marble roller coaster
This is Madeline and her 5th grade science class marble roller coaster - dubbed "Mardi Gras". It's got two loops at the bottom: the regular marble goes through both loops, but the big shooter marble only makes it through the first one. There's an overhead shot of the decoration at my flickr site - just click on the picture.
