What you need

Add multiple drops of color if you want the Oobleck to be a bold color.

Stir ½ cup of water into cornstarch. You should only add half the amount of water compared to cornstarch, at the ratio of 2 cups of cornstarch to 1 cup of water. Use your hand or spoon to mix the water and cornstarch well.

Test Ooblecks by filling a fist and try to make a circle. The hardest thing about making Ooblecks is to prepare the quantity of ingredients. It is difficult to use exactly 2 parts cornstarch and 1 part water. Because of the humidity, the amount of food color and the water temperature also cause changes. When you hold the Oobleck in your hand, it feels like it's melting right in your hand.

If you can't make it round (because it's too thin) add cornstarch, add only 1 tablespoon at a time. Mix well and continue testing.
If the mixture doesn't melt like liquid when you scoop it up with your hands, it's too thick. Now you need to add more water, add 1 tablespoon of water each time.

Method 2 of 2: Use Oobleck

Play with Oobleck. First, hold the Oobleck in hand and then knead, punch, round, let it flow through your fingers into the bowl and mold it into the desired shape. You can also:
- Combine with other colors to create new designs.
- You can place Oobleck in a sieve or basket of strawberries or a similar object to see how it drips down differently from the water.
Experiment with Oobleck. Once you get used to the Oobleck's texture, you should try to see what happens when you squeeze it, or let it sit for a minute and then take it up, how it will look. Here are some experiments you can do with Oobleck:
- Squeeze Oobleck into a ball using your hands around it. Then stop applying the force to the Oobleck and you'll see it drain out of your hand
- Pour a thick layer of Oobleck into the cake mold and pat the surface with your hand. You will be surprised to find liquid still in the tray due to your impact.
- Replace the cake mold with a big crate or large plastic box filled with Oobleck and try jumping on it.
- Put Oobleck in the freezer and see how it goes. Then try applying heat on Oobleck. Is there any difference?
Clean up the Oobleck. You can use warm water to wash Ooblecks from hands, clothes and even on surfaces used for playing or making Ooblecks. When washing dishes, it's okay to let some Oobleck float out, but don't let it run too much into the sink.
- If you let Oobleck dry, it becomes a powder and you can easily sweep it, use a vacuum cleaner to clean it or use a towel.
Oobleck preservation. Place the Oobleck in a box with a lid or a zippered bag. You can then take it out at any time to play. After playing Oobleck is finished you don't Throw it in the sink as it will clog the drain. Instead, you should throw Oobleck in the trash.
