How do you make a super ball out of sodium silicate?
Sodium silicate solution is produced by fusing sand (SiO2)n and soda ash (Na2CO3) in a furnace at about 1300 °C. The final product, Na2O (SiO2)n is also called water glass. The reaction with ethyl alcohol produces a super ball which is most likely a silicone elastomer where the R is (—O—CH2CH3).
How do you make a bouncy ball experiment?
Pour 4 ounces (120ml) of warm water into the cup labeled ‘Borax Solution’ and 1 teaspoon of the borax powder into the cup. Stir the mixture to dissolve the borax. Pour 1 tablespoon of glue into the cup labeled ‘Ball Mixture’. Add 3-4 drops of food coloring, if desired.
What ingredient makes a bouncy ball bounce?
When the glue mixture was added to the borax, the borax acted as a cross-linker, hooking the glue’s molecules together to form the rubbery bouncy ball. The cornstarch was added to help bind the molecules together so the ball would hold its shape. The ball can bounce because of the cross-linked polymers.
How do you make a bouncy ball without baking soda and borax?
To make a bouncy ball, all you’ll need is 2 tablespoons of cornstarch, 1/8 cup of water, and a food coloring of your choice. Start by mixing the cornstarch and water in a microwave-safe bowl. Stir the mixture until it forms a sticky paste. Then, add 1 drop of food coloring and mix it in.
Is sodium silicate water soluble?
Sodium silicates are colorless glassy or crystalline solids, or white powders. Except for the most silicon-rich ones, they are readily soluble in water, producing alkaline solutions.
How do you make a bouncy ball with 3 ingredients?
What is the science behind bouncy ball?
The air in the ball acts like a spring—it gets compressed and expands again. During the collision, some of the ball’s energy is converted into heat. As a consequence, the ball shoots up with less energy than it had when it reached Earth.
How do you make a bouncy ball with silicone and cornstarch?
- Squirt Silicone into cup with cornstarch.
- Add dye, glow, and any other additives.
- Add approximately 1 ML of water (less mater makes it take longer to harden and more water makes it harden faster)
- Mix thoroughly.
- Apply a small amount of cornstarch to hand then put silicone into hand and start rolling.
Can you make bouncy balls without cornstarch?
To make these glitter bouncy balls, you need only three ingredients: 1/2 cup warm water. 1 tbsp Borax powder. Elmer’s glitter glue (I have heard that not all brands of glue will give the same results)
How do you make a bouncy ball squishy?
How do you make a bouncy ball glow?
Is borax toxic?
Borax can cause nausea, vomiting, and diarrhea if you ingest it by itself, and large amounts can lead to shock and kidney failure. It’s banned in U.S. food products. It also can irritate your skin and eyes, and it can hurt your nose, throat, and lungs if you breathe it in.
Which is another name for sodium silicate?
water glass, also called sodium silicate or soluble glass, a compound containing sodium oxide (Na2O) and silica (silicon dioxide, SiO2) that forms a glassy solid with the very useful property of being soluble in water. Water glass is sold as solid lumps or powders or as a clear, syrupy liquid.
What is the pH of sodium silicate?
The molar ratio between silica and sodium oxide (n) plays an important role in the chemical behavior of Na-silicate [11]. It is delivered commercially as a solution with a pH in the range of 11–13 and with a decrease in alkalinity of n.
What is sodium silicate used for?
Sodium silicate has been used to preserve eggs, fireproof fabrics, and waterproof walls. Most commonly, it is used as a cement for abrasive wheels, bonding paper, corrugated boxes and cartons, wood, glass, porcelain, leather, and textiles.
How are super balls made?
The Super Ball was invented and patented in 1964 by chemist Norman Stingley. The ball is made of a synthetic material he called Zectron, using a polymer polybutadiene and other materials, a form of artificial rubber. It was sold to toy stores by the Wham-O company and was, for a while in the 60s, a great fad.
How do you make a bouncy ball with contact solution?
- Fill 1 UHU Glue Pen into a bowl.
- Add food colour.
- Add Glowing Powder to have glowing Slime.
- Add 5 teapsoons of contact lens fluid and 0.5 teaspoon of baking soda.
- Mix again thoroughly. In the end, the Slime should detach well from the sides.
- Knead the Slime and form it to a ball to make it bounce.
What forces are acting on a bouncing ball?
The forces acting on a spinning ball during impact are the force of gravity, the normal force, and the force of friction (which has in general both a ‘translational’ and a ‘rotational’ component).
What energy is lost when a ball bounces?
A Elastic potential energy is what causes a ball to bounce, or rebound. B Each time the ball bounces on the ground, it loses a bit of its kinetic energy.
Why do heavier balls bounce higher?
The air friction is approximately proportional to the square of the radius at high speeds, and to the radius at low speeds. So for bigger balls the ratio of gravitational to frictional force goes up, compared to small balls. That would tend to make the large balls bounce higher.
Is silicone rubber bouncy?
Regular Article. A fluorine-free superhydrophobic silicone rubber surface has excellent self-cleaning and bouncing properties.
How do you make silicone balls?
Is silicone a bouncy?
The bounce property of silicone is about the same as that of compressed rubber.
Can you make a bouncy ball without borax?
