Kiddo is 12, a major Lego fanatic. I'm really looking to expand our building tools here. Snap circuits don't interest him. Knex are a giant NO. Marble runs never held his interest. He loves origami. He loves building. He's used Kapla Blocks at the science center but there are usually so many dang kids around my own kiddo can't finish a project or concentrate.
My basic questions:
1. Why are these things so dang expensive? They look like popsicle sticks
2. Do your kids like them, do you think my kid would?
3. How many do you realistically need?
4. Does the color make a difference?
