Drag body rig is anything but.

March 26 Emflume drag body velocimeter development. from 史蒂夫 · 高夫 on Vimeo.

A few times each year I have an exciting, emotional day in the lab.

When I realize I’ve done something that will make the world a better place.

Watch the movie.  I loved building this drag body velocimeter and playing with it.  I can’t imagine a better way for students to get a hands-on, physical, visual understanding of how moving water works.

After more work, we’ll ship this worldwide, and thousands of students will use this simple, inexpensive, elegant device to love and enjoy learning like I did this week.
