I take it that this is not a mommy and me thing, lol. I think it is cool. I dated a guy once who built these from scratch and put the boards in some kind of fluid. He even built a Jacobs Ladder and made ozone to take the smoke smell out of a basement. I am clueless about such things. My daughter was labeled learning disabled and took forever to read. She was put through so much reading help that she fell behind in math. Then come to find out after another teacher took interest and tested her, she is labeled a visual spatial learner. To make a long story short, Vs learners see the whole and then break it down, most of us learn the opposite way, by being given parts to put together. Schools teach to the majority and VS learners fall behind, so I am constantly seeking hands on items she can learn from because she is actually quite smart.
