Wooooooahhh! vs Aha!, is the choice obvious?

There has been a lot of focus towards attracting people, especially under-represented groups, to STEM fields. One of the ways to accomplish this is short demonstrations and workshops, where young students are exposed to ``exciting'' experiments in an effort to make STEM more appealing. We tried an alternative approach by making the students perform a deliberately ``boring'' experiment but one which made them think scientifically. This was tested on a small group of high school students during Girls Technology Day in New Hampshire.
