Okay. That's what I wanted to know.
You're certainly on the mark here in terms of the degree to which these kinds of operations and exhibits and facilities help engender young people to look at science.
I wonder if you could give us some statistics on what that looks like and what kinds of results. Do you have anything that shows that the exposure to these kinds of exhibits and organizations in fact drives higher numbers of graduates, for example, or greater enrolment in science and math? Is there anything like that that demonstrates those results?
