When you were little, did you like to experiment? If you have a child, it’s time to take your first toys apart, taste inedible things and find out what is unfamiliar or already forgotten. Your children will learn the world all the time, and you should help them with this. Home experiments will allow them to understand the world. See how much fun you can enjoy studying chemistry or physics!
Tea Rocket
You will need:
- tea bag;
- lighter or matches;
- iron tray.
Carefully cut the tea bag and sprinkle the contents, but do not discard. Then form an empty bag in the cylinder so that you can easily put it on the tray, and pour the tea leaves on top. Our rocket is ready!
Finally, set fire to the top of the bag and see what happens. It is because of the small weight of the tea bag that the flow of hot air allows it to fly up.
Home volcano
You will need:
- baking soda;
- gouache or any red paint;
- dishwashing liquid;
- lemon acid;
- box;
- polymer clay.
Make a cone out of cardboard and cut off its tip so that a hole with a diameter of several centimeters is formed. It is best to fix the cone with a stapler. Then place an empty bottle or flask inside and wrap the entire cone with clay to resemble a real volcanic mountain. Place the resulting volcano on a tray or in a large deep plate to protect the room from a huge volcanic eruption.
Pour soda into any container, about five tablespoons, add red paint and water, then add a drop of dishwashing liquid. Mix everything thoroughly, pouring the resulting mixture into the mouth of the volcano. Finally, let your child pour citric acid in water onto the volcano. Now enjoy the volcanic view!
When soda and citric acid are combined, a violent reaction occurs, as a result of which water, salt and carbon dioxide are formed.
Flying balloons
You will need:
- 1.5 liter bottle;
- tea spoon;
- funnel;
- vinegar;
- baking powder or baking soda;
- Balloons.
This experiment must be performed with rubber gloves and glasses! Fill 1/3 of the bottle with vinegar and pour 2-3 teaspoons of soda or baking powder through the funnel. Put the ball on the neck of the bottle. Unfortunately, balloons filled with carbon dioxide will not be able to fly, but when you need to attach a balloon to the ceiling, rub it on your hair. Thanks to the experiment, he definitely will not fall over time.
Carbon dioxide, which fills the ball, is formed as a result of the reaction of soda and vinegar. Rubbing the surface with synthetic material, we charge it with an electrostatic charge, thanks to which it can remain on the ceiling for up to five hours!
Fluid layers
You will need:
- fruit juice;
- vegetable oil;
- alcohol;
- paint;
- clear glass.
Pour the juice into a transparent container, a tall glass is best, then slowly pour the vegetable oil over the wall of the container. Add a little paint to the alcohol to get a color, and carefully pour it into the oil. All liquids will create three separate multi-colored layers.
This happens because substances have three different densities, so they do not mix with each other.
Soft egg
You will need:
- 2 eggs;
- 2 cups or glasses;
- water;
- vinegar.
Place one raw egg in a cup of clean water and the other in a glass of vinegar.The eggs look the same, right? Now set them aside for a few hours. The first differences are visible already 6-7 hours after the start of the experiment, and after 7-10 days the vinegar egg will become completely soft, as its shell will disappear.
The eggshell consists of calcium, which dissolves under the influence of vinegar. During the reaction between calcium and vinegar, carbon dioxide is formed. When the hard shell dissolves, it becomes a soft transparent film.
