8 simple but interesting scientific experiments you can try at home

Not difficult to implement, easy to find materials and interesting results are the things you will experience through 8 simple science experiments in this article.

It seems that science is dry and confusing things, but if you understand the basic theory, you can completely make interesting experiments at home.

Tests introduced in the article introduced by Business Insider use only popular and easy-to-find materials and chemicals at chemical stores outside the market. Besides, the implementation is also quite easy to do at home.

1. Make tornadoes in a water bottle

You can make tornadoes inside a water bottle by utilizing the vortex principle by shaking the bottle vigorously and creating a bottleneck. All the necessary tools include two water bottles, one connecting two bottles and water. To see more clearly the tornado, you can add color to the water.

2. Rainbow in glass bottles

Experiments use color and density to create different color layers that make you think of rainbow colors. To do this, you will have to add sugar to the cup. The color layer will be the top layer and the density between the color layers will create a certain interference like a rainbow.

3. Make a large plastic block to play with

When you mix glue, water, a little color and add a little borac, they will create a special kind of plastic. The reason this mixture creates a plastic form is in polyvinyl acetate glue (vinyl acetate), a form of liquid polymer. And borac is able to bind polyvinyl acetate molecules to make larger polymers.

4. Making rocket engines

You can completely create a special rocket engine from yeast, hydrogen peroxide, glass bottles, fire and . an uncooked pasta fiber.

When you mix yeast and hydrogen peroxide together, they react and produce oxygen (O ₂ ) or oxygen. When O ₂ escapes through pasta, you simply need to light the fire at the tip of the pasta as the fire can flare up like a real rocket engine.

5. Homemade lava lamps

Alka-seltzer is an effective remedy for heartburn or abdominal pain. However, they can even be used to make homemade lava lamps quite interesting. To make homemade lava lamps, you will need water and oil to eat with an Alka-seltzer tablet.

Because oil and water have different densities and poles, when you mix them, the water will settle to the bottom and the oil floats upward. To get the best view of the submerged water, you can add a little color to it.

When an alka-seltzer tablet is released, it reacts with the water and causes the droplets to quickly spray up (aerosol form) but due to the oil blocking, the air bubbles continue to sink to the bottom. This interesting reaction reminds you of the lava lamps commonly found on the market.

6. Turn water into ice immediately

In order to quickly turn water into ice, this experiment will need a block of ice. That's how it applies to normal water when containing particles and impurities. But with pure water, everything is completely different. They can reach temperatures even lower than normal water before freezing.

Pure water can freeze and cool to -40 degrees C. If you put a bottle of pure water unopened in the refrigerator in less than 3 hours, the bottle will even be cold below freezing temperatures. usually, common, normal.

By applying this principle, you only need to pour this super-cold water onto a small block of ice, which will quickly turn into cold ice immediately.

7. Performance with ferromagnetic water

This interesting experiment will allow you to observe the magnetic field. All the essentials are iron oxide, water and a glass jar. When you place an extremely strong magnet outside the glass bottle, the iron oxides inside the water will quickly be drawn up, stacked, even move around the jar when you put the magnet on the outside. .

8. Volcanic lava made of soda

In this experiment, we will apply a chemical reaction between baking soda and vinegar to create a life-like lava eruption effect.

You will need to prepare a mixture of baking soda, vinegar and an artificial volcanic model. The reaction between vinegar and baking soda will produce CO2, the pressure created in the volcanic model will form air bubbles and cause an eruption reaction.
