Liquids flow and take the shape of the container they are in. You can see that happen when you pour a glass of water. Usually matter turns into a liquid when it is heated. Water has a low viscosity and flows fast. Honey has a high viscosity and flows slowly.
If you heat honey or lava…it flows faster. Mix up this corn starch Goo and see how it behaves. Is it a liquid or is it a solid? Put 1 cup of cornstarch or borax in a mixing bowl. Mix the goo with your hands until it starts to feel like a sticky glue. Try to pick up a handful of the goo.
Squeeze your hand around the goo to make a fist around it. What happens? Now relax your hand. What happens now? Pour the goo onto a cookie sheet or tray.
Make sure the sheet or tray has sides! Lay your hand on top of the goo and leave it there for a few seconds. Pull your hand straight up and watch what happens. Cornstarch or borax goo is an anomaly - that means it's weird! It doesn't act like it should. Your Ooze is made up of tiny, solid particles of cornstarch suspended in water.
Chemists call this type of mixture a colloid. As you found out when you experimented with your Ooze, this colloid behaves strangely. When you bang on it with a spoon or quickly squeeze a handful of Ooze, it freezes in place, acting like a solid. The harder you push, the thicker the Ooze becomes. But when you open your hand and let your Ooze ooze, it drips like a liquid. Try to stir the Ooze quickly with a finger, and it will resist your movement.
Stir it slowly, and it will flow around your finger easily. Smack water with a spoon and it splashes. Smack Ooze with a spoon and it acts like a solid. Most liquids don't act like that. If you stir a cup of water with your finger, the water moves out of the way easily--and it doesn't matter whether you stir it quickly or slowly.
Your finger is applying what a physicist would call a sideways shearing force to the water. In response, the water shears , or moves out of the way. The behavior of Ooze relates to its viscosity , or resistance to flow. Water's viscosity doesn't change when you apply a shearing force--but the viscosity of your Ooze does. Back in the s, Isaac Newton identified the properties of an ideal liquid.
Water and other liquids that have the properties that Newton identifies are call Newtonian fluids. Your Ooze doesn't act like Newton's ideal fluid. This versatile product is made from the kernel of the corn plant, specifically the starchy part known as the endosperm. How do you make slime with dish soap and cornstarch? How to make it.
Mix until is is well combined. Them get your hands in there and mix it until it becomes oozy, gooey loveliness! My kids played with this for ages! How do you make slime with cornstarch and conditioner? Instructions Place the cornstarch in a large bowl. Mix in the hair conditioner with your hands—it will just start coming together and it will be pliable and very, very smooth.
If desired, add a drop or two or food coloring. You may need to add more conditioner as you go. Use food coloring to color as desired. How do you make activator? Once you have your 1 cup of hot water you are going to then add the 1 tsp of borax powder to the water. Stir well until all the powder is dissolved.
Let cool before using. So now you that you have your slime activator it's time to put it to use. How do you make slime with dish soap? Add tablespoons of water and stir.
The mixture will start to foam, at which point you can add in your favorite color of food coloring. Add one cup of baking soda to the mixture and stir. How do you make the perfect cloud slime? Add in your slime activator, the liquid starch, to complete the chemical reaction to make slime. Add the activator slowly. Who makes Campbell Hausfeld air compressors?
