KANSAS CITY, Mo. (AP) — Science City at Kansas City’s Union Station is rebounding from years of stagnant attendance, thanks to new exhibits and attractions and an increase in donations.

The latest good news came Wednesday, when two new exhibits costing more than $1 million and resulting from a high school science competition opened.

The Kansas City Star reports  more than half of Science City has been overhauled in recent years, sparked by more than $5 million in donations from the Burns & McDonnell Foundation and in-kind services from the company.

It appears to be paying off. Attendance at Science City increased 7 percent in 2013 and has grown by double digits this year. Revenues increased 17 percent in 2013 and Union Station CEO George Guastello says the science center is financially self-sustaining.
