Picture of Oobleck: The Dr. Seuss 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. 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. Make enough Oobleck and you can even walk on it!

Oobleck gets its name from the Dr. Seuss book Bartholomew and the Oobleck where a gooey green substance, Oobleck, fell from the sky and wreaked havoc in the kingdom. Here the Oobleck will be made in a bowl and will likely make a mess, but only because you can get carried away playing with it.

Step 1: Materials

Picture of Materials
All you need is corn starch and food coloring and the food coloring is optional.

- 1 cup water
- 1.5-2 cups corn starch
- a few drops of food coloring of your choice

Step 2: Mix it up!

Picture of Mix it up!
Start with the water in a bowl and start adding the corn starch to it. You can use a spoon at first, but pretty quickly you'll be moving on to using your hand to stir it up.

When you're getting close to adding 1.5 cups of the corn starch, start adding it in more slowly and mixing it in with your hand. The goal is to get a consistency where the Oobleck reaches a state that is the liquid and yet solid.

Sometimes you will need more cornstarch. If so, keep adding more than the initial 1.5 cups. If you add too much, just add some water back into it. You will have to play with it to see what feels appropriately weird.

great for kids.

Using a speaker/subwoofer is a great addition.

I used an Android app in order to generate frequencies. Works best between 28 and 35Hz (in my case).

I am sure will depend on the type of tray being used.

Wouldn't it be easier to add the food coloring to the water before mixing the water & corn starch?
