    Under Pressure, Part 2

    Our adventures with pressure continue after the trip to the aquarium. To see just how much pressure we could generate with height, A.J. and I teamed up with the Corvallis Fire Department to recreate an experiment attributed to 17th-century French physicist Blaise Pascal. In Pascal’s experiment, he (supposedly) used a column of water to burst a wooden barrel. In ours, we use a ladder truck to make a 30-meter column of water burst a glass carboy! We also got a little help from our friends at the Lutetium Project to introduce you to Pascal and his work. (Thanks, Guillaume!) We’ll tell you more about Pascal and his contributions in an upcoming video, so stay tuned. (Video and image credit: A. Fillo and N. Sharp)

    Under Pressure

    Pressure is a concept that can be unintuitive, but it’s incredibly important in physics and engineering. So I’m excited to debut a collaborative video series that @mostlyenginerd and I are producing all about hydrostatic pressure! Today’s video is one of our openers: it focuses on where pressure comes from and why it’s a function of height but not volume. And to show you just how pressure increases with depth, we teamed up with divers from the Oregon State University Scientific Diving Team and headed to the Oregon Coast Aquarium’s Halibut Flats exhibit. Ever seen what a balloon looks like 7 meters underwater? You’re about to! (Video and image credit: N. Sharp and A. Fillo)
