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 causes the Oobleck to move?

A quick tap on the surface of Oobleck will make it feel hard, because it forces the cornstarch particles together. Moving slowly gives the cornstarch particles time to move out of the way. Oobleck and other pressure-dependent substances (such as Silly Putty and quicksand) are not liquids such as water or oil.

How do you make a big batch of oobleck?

Mix A Batch: The secret to a good oobleck is a complex mixture of … one cup water to 2 cups of cornstarch. If you want to make larger batches, you’ll need to … just keep that 2-to-1 ratio. Then stir it with a spoon until smooth.

Can you walk on oobleck?

The solid zone started to melt away. Basically, the only way not to get stuck or fall through the oobleck is to continue applying force to the particles. Ultimately, this explains why you can’t walk on water, but can on oobleck. The viscosity, or thickness, in “normal” fluids (like water) stays constant.

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.

How do you make an Oobleck science experiment?

Directions

1. Ask student to create a testable question (a hypothesis).
2. Put 1 cup of water in a bowl and gradually add the cornstarch to it.
3. Mix and blend very well.
4. If desired, mix in a few of drops of food coloring.
5. Play!
6. Bonus: Use a large plastic bin or tub to make a big batch of Oobleck.

How long can Oobleck last?

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. Do not pour Oobleck down a drain! We put all of the Oobleck into the bin used for the walking activity and then disposed of it.

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.

Can you make Oobleck with flour and water?

Can you make Oobleck with flour and water? Flour (standard wheat flour) will not make Oobleck. Once combined with water, it will create a paste instead, which is how a simple homemade glue is actually made.

Can oobleck be saved?

To store oobleck let it dry out in a bin open to the air, then refresh it with water when ready to use again. I tried storing it in an airtight container and after few days it spoiled.

How do you make the Oobleck dance on Babble dabble?

Play a low frequency test tone and hold the plastic lid tightly against the subwoofer. Alternatively use your fingers to stretch plastic wrap over the subwoofer and hold in place. The vibrations in the subwoofer will begin to make the oobleck vibrate and cause it to lift up and “move” in a weird and wonderful dance.

What’s the best way to do the dancing oobleck experiment?

Lids work well because they have edges that will contain the liquid. Place a few tablespoons of oobleck on the lid or plastic wrap. Play a low frequency test tone and hold the plastic lid tightly against the subwoofer. Alternatively use your fingers to stretch plastic wrap over the subwoofer and hold in place.

How much corn starch do you need to make dancing oobleck?

About 2 cups of Corn Starch to 1 cup of water. Once your recipe is ready let the kids play for a bit while you set up the next step. a MP3 of an audio test tone ~ you will have to play a bit to see what works best with your equipment.

How can I make my speaker sound like an oobleck?

Start your signal/tone generator app and begin playing a tone. Start Google’s Science Journal app and create a new experiment using the sound level sensor. Begin slowly increasing the volume of the speaker until you see the Oobleck begin to clump and move around like a creature from an old sci-fi movie.
