It's always so fun to watch people play. Earlier this week I was watching kids build marble tracks on the floor and came up with an idea to build marble tracks off the wall with simple materials. Like I say in the video, the prototype I came up with is very delicate and I was easily frustrated by the smallest adjustment throwing off the whole alignment of the track. I do like how simple the materials are and that it packs up easily into a small box. There are some preparations and things to build for the elevation points and the track sections shown in the photos and video.
Prototyping and playing with this was important for me to get the idea out of my head and into my hands. Although it's not the most durable and I got frustrated by how delicate it is, making this lead to some other ideas for track-based marble runs.
