In comparison to other science centres I have visited, this one is mediocre. While it was certainly entertaining for the kids, there was not much educational value in it. Explanations would improve many of the experiments. One notable exception was the little show with experiments on temperature, which was very nicely done.
Overall it was more of a playground than a science centre.
The adults in our company missed chairs to sit on while waiting for the kids. There is nothing to sit on within the exhibits that is not part of the actual experiments.
For what it is, I think the place is too expensive (20$ for adults, 16$ for teens and 13$ for kids under 12). A family of four can easily spent 100$ on entrance fees, parking and average quality cafeteria food.
