ID Code: A1-43
Purpose: Visualize three-dimensional figures
Description: Plastic frame with two colored rods. The trick here is to determine, solely by looking at the frame from two sides set 90o apart (as seen above) whether the sticks are touching or not. The video, below, of the frame rotating reveals the answer.
Availability: Available
