For our family for three it cost us $15, so it's relatively inexpensive compared to a number of rainy day options.
The facility is out-of-date, but there are enough fun little contraptions to occupy the family for close to an hour or so.
The exhibits are old and mostly basic science, but if you take the time to read and explain these to your child it can be fun. Our daughter is just about seven and it was fun.
Yes it's not the most exciting place, but if you don't want to drop tons of $$ at an arcade, the movies, or bowling, you can survive part of a rainy day at this place.
