The listing, Marble Works Deluxe Set by Discovery Toys Set 1 has ended.
More photos are forth-coming.
Marbleworks® Deluxe Set by Discovery Toys. In their catalog these sets run brand new for about $75. Here is their description of what these toys do:
"Connect colorful tubes, chutes and bases together in different ways to create an infinite number of raceway configurations. As the marbles speed through the course, children learn about the laws of gravity, object permanence and cause and effect.
Marbleworks products inspire girls AND boys to pursue higher education in the fields of engineering, math and technology."
Kids and even adults of all ages enjoy these sets. I have put together 3 identical sets that contain more parts than what DT puts in their boxes. Some are not in perfect condition, but all parts are still usable. e/d
