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 makes homemade bouncy balls bounce?
Store-bought bouncy balls are made of rubber, another material that is made up of polymers. When the bouncy ball is stretched, these polymer chains uncoil and straighten. When released, the chains coil back up again. This makes the material stretchy and bouncy.
What is the science behind ball bouncing?
When a bouncing ball falls, it initially gains speed or kinetic energy—the energy of motion. The ball slows down, deforms temporarily and shoots back up. 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.
How do you make a bouncy ball egg?
Instructions
- Place egg carefully in the jar. If the shell breaks at all, you will need to use a different egg.
- Pour vinegar into the jar until the egg is covered. Cover the jar and wait!
- 24 hours later, drain the vinegar and refill again. Let the egg sit for seven (7) days.
- Remove the egg and rinse off.

- food coloring (optional)
What does friction do to a bouncing ball?
Since the friction force is opposite of the ball’s spin, it torques the ball in the other direction. It also causes the path of the ball’s bounce to skew in the direction of the friction force. When a ball hits a wall or surface, it makes a noise, which is a loss of energy from the ball’s bounce.
Why does soaking an egg in vinegar make it bounce?
If you soak an egg in vinegar the eggshell will absorb the acid and break down, or dissolve. The calcium carbonate will become carbon dioxide gas, which will go into the air. What is left is the soft tissue that lined the inside of the eggshell. It will bounce!
How do you make a bouncy egg that won’t break?
The Rubber Egg Experiment
- Place an egg in a cup. Place a raw egg carefully in a clear jar or cup.
- Add vinegar. Pour enough vinegar in the cup to completely submerge the egg.
- Add food coloring. Add in a few generous drops of food coloring and stir gently.
- Wait! Observe the eggs each day.
- Rub off the shell.
- Bounce it!
