  • Biking Across a Pool of Cornstarch – Hard Science

    Partilha no teu site ou blog:

    Want to see Anthony get shot in the chest? SHARE THIS VIDEO! When we reach 100 shares, we’ll publish a video of Tara shooting Anthony, using only a bag of cornstarch and water as a shield.

    Think it’s impossible to walk on liquid? Think again. Join Anthony and Tara as they make a pool of non-Newtonian fluid, out of oobleck, and walk, run, jump and bike across it. Thanks, science, for the awesome cornstarch pool party!

    Experiment Tips:
    • Use one part water, two parts cornstarch
    • Walk quickly, the faster you go the more solid it feels
    • Add food coloring to observe how it moves

    A Liquid and a Solid

    “In non-Newtonian fluids, the particles are packed very close to each other (they are touching), but they are still able to slip by each other. When you move the mixture slowly, the suspended particles have time to move and slip by each other — this is how a normal liquid acts. However, when you suddenly apply pressure to the mixture, the particles do not have enough time to move out of the way as they are quite large. This causes them to stay right where they are which causes the mixture to act and feel like a solid.”

    Putting the Newton in Non-Newtonian

    “The term “Newtonian” was named after Sir Isaac Newton (1642-1727), a scientist who came up with the three laws of motion and was described as “the most important contributor to the development of modern science”

    Dancing Non-Newtonian Fluid

    How does non-Newtonian fluid react on speakers?

    Join Anthony Carboni and Tara Long as they turn the world around them into a giant science experiment. New episodes every Wednesday!
