What force makes Oobleck dance?
When the speaker is off, there is no force or pressure acting on the oobleck so it reacts as a liquid. The oobleck responds to the low frequency sound waves as they exert a greater force and pressure onto the oobleck, causing it to move and dance as a solid.
What is the ratio of cornstarch to water for Oobleck?
To get measure out the ingredients for oobleck, we recommend starting with 1.5 tablespoons of corn starch and 1 tablespoon of water. The ratio should be able 1.5-2 parts corn starch to one part water. Mix well, stirring all the corn starch into the water.
Why does Oobleck dance on a speaker?
But more vibrations don’t equal more movement of the non-Newtonian fluid. Instead, it is the lower pitched (lower frequency) sounds that cause the oobleck to shake. Although there are fewer vibrations per second at lower pitches, these frequencies cause more motion in the speaker cones.
How do you make Oobleck in the classroom?
For the proper making of Oobleck:
- Mix the cornstarch and water in a large bowl.
- Mix it with your hands for the right consistency (add water or cornstarch as needed to get the right consistency)
- Place the 3 bowls out for people to see.
- Use the cleaning supplies to clean the area and hands.
Can Oobleck get moldy?
Oobleck can be kept in an airtight container for 24 hours, but may require more water before it becomes the right consistency again. Dispose of Oobleck after 24 hours or it can develop mold.
What is Oobleck made of?
Oobleck is actually a pretty simple mixture of cornstarch and water. Its common name (which I later learned is not what all kids call it) comes from a Dr. Seuss story, Bartholomew and the Oobleck, where a young boy’s wish for something other than rain or snow to fall from the sky is granted.
Will Oobleck stop a bullet?
Lightweight body armor uses liquid to stop bullets. … Upon first examination, oobleck looks and acts like any other liquid. It flows from one cup to another easily like you would expect. However, if you apply sudden, sharp force to the surface, it becomes a near-solid mixture.
Do you need warm or cold water for Oobleck?
You can use warm water to clean the Oobleck off your hands, clothes, and even off of your counter. You can rinse a bit of it out of your bowl, but make sure not to let too much of it get down the sink. If you let it dry out, it turns into a powder that is easily swept, vacuumed, or wiped up.

What happens when you put Oobleck on a speaker?
The Science Behind the Experiment Sound can be transmitted through air, water, and solids. As the subwoofer produces a sound, it’s surface vibrates along with the lid on top. When you put oobleck on the lid, the vibrations move through it and you can “see” the sound waves.
How do you make large amounts of Oobleck?

What is Oobleck Experiment?
Oobleck is a classic science experiment that’s perfect for entertaining both kids and adults. Oobleck is a non-newtonian fluid. That is, it acts like a liquid when being poured, but like a solid when a force is acting on it. You can grab it and then it will ooze out of your hands.
Can you swim in Oobleck?
Oobleck is unique because it can behave as both a solid and a liquid. If you could go swimming in a pool of oobleck, the oobleck would feel like a liquid when you moved slowly, but would act like a solid if you tried to swim around quickly. The Oobleck mixture isn’t your typical liquid—or solid.
