What is the science behind oobleck?

Unusual fluid

Oobleck is a non-Newtonian fluid, a term for fluids that change viscosity (how easily they flow) under stress. When you run your fingers slowly through cornstarch and water, it acts like a liquid, but apply rapid force, and it solidifies, bends and even tears.

What is the science behind oobleck for kids?

Oobleck is a mixture of a solid (corn starch) suspended in a liquid (water). Oobleck behaves like a solid when force is acted on it quickly. This is because the pressure forces all the particles of corn starch together and they behave like a solid.

Is making oobleck a science experiment?

Oobleck is a classic science experiment that’s perfect for entertaining both kids and adults. If you haven’t seen it in action it’s very fascinating stuff and before too long you’ll have your hands covered with it, happily making a mess that can be washed away with water. Oobleck is a non-newtonian fluid.

Is oobleck a solid or a liquid and why?

Oobleck is a non-Newtonian fluid; it has properties of both liquids and solids. You can slowly dip your hand into it like a liquid, but if you squeeze the oobleck or punch it, it will feel solid.

What is the science behind oobleck? – Related Questions

Can oobleck stop bullets?

Is oobleck edible?

Luckily, the gooey substance is not toxic, but it probably won’t taste good since it’s just cornstarch and water. As one individual pointed out on Yahoo Answers, while eating oobleck may not be poisonous, it could potentially give someone pains in their stomach if large quantities are ingested.

How is oobleck both a solid and a liquid?

Why does oobleck become a solid?

When you apply pressure to oobleck, it works the opposite of the previous examples: The liquid becomes more viscous, not less. At the places you apply force, the cornstarch particles get mashed together, trapping water molecules between them, and oobleck temporarily turns into a semi-solid material.

Is oobleck a fluid?

Oobleck is a non-Newtonian fluids of the opposite variety ketchup, and in a bottle it should behave opposite to ketchup- it will flow out easily when inverted but won’t flow when you smack, squeeze or shake it.

What state of matter is oobleck?

Oobleck is a non-Newtonian fluid or liquid. Under pressure it behaves like a solid.

Who invented oobleck?

Non Newtonian Fluids, of which Oobleck is one, were described by Sir Isaac Newton around 1700.

What happens if you freeze oobleck?

Freezing the oobleck creates a solid. As the oobleck melts, the consistency keeps changing. This will keep your child interested for quite a while.

Can oobleck get moldy?

As oobleck is technically a food product, it can grow mold, although this is most likely to occur if the oobleck is stored using improper storage methods and is kept this way for an extended period of time. If the oobleck is not stored correctly, then it can begin to grow mold after three or four days.

Can you bake oobleck?

*You can also put the oobleck in an oven-proof dish and place it in the oven on the lowest heat setting for 2-3 hours.

What happens when you put oobleck in the microwave?

Heating the Oobleck changed it from a non-Newtonian fluid back to a solid. Removing the water from Oobleck stopped the material from flowing. Adding water back into the mixture, however, returned the material back into a non-Newtonian material.

Can oobleck dry up?

If oobleck is left out too long, it will dry out and turn back to cornstarch.

Will oobleck stop an egg from breaking?

The Oobleck protects the egg. When it hits the ground, a quick direct force is applied to the Oobleck. The cornstarch clumps together and hardens like a solid, absorbing the impact and protecting the plastic egg.

Can you put glitter in oobleck?

We added sparkle to one of our favorite sensory recipes by including glitter! We love the way oobleck changes between the properties of a liquid and a solid as a non-Newtonian fluid. To make oobleck you only need corn starch and water!

Is oobleck and slime the same?

Oobleck was the name given to a type of slime in a Dr. Seuss book that was capable of gumming up a whole kingdom. The oobleck that you can make for a science project isn’t gummy, but it does have interesting properties of both solids and liquids.

Is ketchup a oobleck?

Another non-Newtonian liquid is ketchup. Ketchup behaves in the opposite way from Oobleck. You could even call it the “anti-Oobleck.” It becomes less viscous when agitated. Liquids like this are called shear thinning liquids.

How long will oobleck last?

Oobleck is great for days of play. To store, put oobleck in an airtight container and refrigerate. You may need to add a splash or two of water to get the desired consistency again. Store and reuse for up to two weeks of fun.
