 Supplemental Programs

Many of our pages use supplemental programs that "plug in" to the web browser, to increase interactivity. Although several of these are likely to be active on your computer already, we have provided links to allow you to download free readers. We have also included a quick check so you can see if each program is installed and working on your system.

Macromedia Flash Player
Flash Player allows you to view and interact with many of our animations. If you have Flash Player, the anhimation below should be visible.

If not, go to the Macromedia Flash site, and click the button that says, "Install Now." A new page should load telling you that installation is complete. If a warning window pops up, click the "Yes" button at the bottom.

Apple QuickTime
Quicktime is a movie-viewing program. Systems with QuickTime installed should display the movie of bubbles in a wave below.
