Introduction: Embarking on a Scientific Journey

Welcome to this exciting video experience! I have always dreamed of conducting experiments, and today, that dream is becoming a reality. I purchased a little chemist's kit that cost 30 euros, even though 80% of the experiments were a bit underwhelming. However, there was one experiment that turned out to be quite enjoyable, so I decided to go ahead and try it.

We're not just going to do experiments from the little chemist's kit, because that would be rather boring and not very impressive. Instead, I've combined various things to create a more diverse range of experiments. We're going to create a lot of fire, make an erupting volcano, engage in some milk magic, and much more. Stay until the end of the video, because it's going to get increasingly exciting!

Experiment 1: Creating a Non-Newtonian Fluid

For our first experiment, we're going to create a simple non-Newtonian fluid, which you've likely seen many times on YouTube. You might be wondering, 'What's so special about a liquid that becomes solid when you exert force on it?' Well, let me explain.

We're going to use the magic of corn starch for this experiment. When corn starch is mixed with water, the mixture becomes liquid if you move slowly, but turns into a solid if you apply rapid force. The reason for this is that when you apply gentle pressure, the starch molecules remain dispersed in the water. However, when you exert sudden force, the molecules cluster together and form a solid.

To begin, we'll mix two doses of corn starch with just enough water to create a smooth mixture. Once we have the right consistency, we can experiment with the non-Newtonian properties of the fluid. If I slowly insert my hand into the mixture, it will feel like a liquid. But if I apply sudden force, it will become solid, resembling a wall.

Experimenting with the Non-Newtonian Fluid

As we start to play with the mixture, you'll see that if I slowly move my hand through it, it behaves like a liquid. But if I suddenly apply pressure or try to punch it, it becomes solid and resists my force. It's almost like there's a wall inside the liquid. This is the magic of non-Newtonian fluids. They can act as both liquids and solids, depending on the force applied to them. It's a fascinating concept and really highlights the fascinating nature of science.

Experiment 2: Invisible Ink Messaging

Have you ever dreamed of creating secret messages using invisible ink? Well, today I'm going to teach you how to make your own invisible ink solution. It might not be as advanced as something you'd see in spy movies, but it's still a lot of fun.

To make invisible ink, you'll need a glass of water, some salt, a paintbrush, and a sheet of black paper. First, we'll add about 20 milliliters of water to a container. Then, we'll add a few teaspoons of salt and mix it all together until the salt has dissolved.

Next, we'll take the paintbrush and dip it into the saltwater solution. We can now start writing our secret message on the black paper. As we write, the message will be invisible, thanks to the clear saltwater solution.

Revealing the Secret Message

After writing our secret message, the paper will appear completely blank. But if we wait a while, the salt crystals in the saltwater solution will start to reappear, slowly revealing the hidden message. It's important to note that this method takes time to fully reveal the message. In my experiment, it took about half an hour for the salt crystals to start appearing. So, if you try this at home, be patient – the full message might not become visible for a few weeks!

Experiment 3: Milk Magic and Color Diffusion

For our next experiment, we're going to create something poetic – a beautiful display of colors and patterns using milk, food coloring, and dish soap.

To begin, we'll take a plate and pour a small amount of milk into it, just enough to cover the bottom. Then, we'll add a few drops of food coloring – blue, red, and yellow – in different spots on the milk.

Next, we'll take a small piece of cotton and roll it into a ball. We'll then cover the cotton ball with a little dish soap. Now, get ready for the magic! When we place the soapy cotton ball into the milk, it will cause the colors to swirl and diffuse in a mesmerizing pattern.

Understanding the Science Behind Color Diffusion

The reason for this colorful display is due to the properties of both milk and dish soap. Milk is composed of fat molecules, while dish soap is bipolar – one part loves water, and the other part doesn't. When the soapy cotton ball is placed in the milk, the molecules in the soap that love water attach to the water molecules in the milk, while the soap molecules that dislike water attach to the fat molecules. This creates a frenzy of movement, causing the colors to swirl and diffuse in beautiful patterns.

Experiment 4: Exploding Balloons with Juice

This next experiment might not seem too exciting at first – it involves inflating a red balloon. But when we combine the balloon with a little bit of juice, something magical happens.

To begin, we'll inflate a red balloon and tie it off. By itself, the balloon is quite ordinary. However, if we pierce the balloon with a small object and then squeeze a bit of juice into it, something incredible occurs – the balloon explodes!

It's important to note that for this experiment to work effectively, the balloon should be almost completely deflated before adding the juice. If there's too much air inside, the explosion will be less dramatic.

Understanding the Science Behind the Exploding Balloon

The reason for the balloon's explosive behavior is quite simple – it's due to the rapid expansion of gas inside the balloon. When we add the juice to the nearly empty balloon, it mixes with the air remaining inside, creating a gas that expands very quickly. This rapid expansion of gas puts immense pressure on the balloon, causing it to burst in a spectacular fashion. It's a fun and visually impressive experiment that demonstrates the power of gas expansion in a simple yet exciting way.

Experiment 5: Reigniting a Flame with Smoke

For this next experiment, we'll explore the fascinating relationship between fire and smoke. We'll use a candle, a glass, and a spoon to demonstrate how smoke can actually reignite a flame.

First, we'll light a candle and let it burn for a little while, allowing it to create some smoke. Then, we'll carefully extinguish the flame using the spoon or a glass. Now, here's where the magic happens – if we hold a lit match near the smoke coming from the extinguished candle, we can actually reignite the flame using the smoke itself!

This might seem like an impossible feat, but there's a scientific explanation behind it. The smoke from the candle contains tiny particles of soot, which act as a fuel source. When we introduce a flame to these soot particles, it ignites them, creating a pathway for the flame to travel back to the candle wick and reignite the original flame.

Experiment 6: Creating Paper Rockets

For our next experiment, we're going to create some simple paper rockets using tea bags and a little bit of fire. This is a fun and easy project that can be enjoyed by both children and adults.

To begin, we'll collect several tea bags – I used orange cinnamon tea bags because they seem to work best. We'll carefully open each tea bag and empty the contents onto a plate. Then, we'll remove the paper filter from the tea bags and discard it, leaving only the dried tea leaves.

Next, we'll take the tea leaves and roll them into small tubes, creating a shape that resembles a tiny rocket. Once we have several of these paper rockets ready, we can start experimenting with launching them.

Launching the Paper Rockets

To launch the paper rockets, we'll hold a lighter or match near the bottom of the rocket and let the tea leaves catch fire. As the leaves burn, they create a small amount of gas that propels the rocket upwards. It's important to be careful when working with fire, especially if there are children present. Make sure to have adult supervision and take all necessary safety precautions. When done correctly, this experiment can be a lot of fun and a great way to introduce kids to the basics of rocket propulsion.

Experiment 7: The Freezing Fireball

One of the most anticipated experiments in this video is the creation of a freezing fireball. This fascinating demonstration combines the concepts of fire and cold in a visually stunning way.

To create the freezing fireball, we'll take a piece of cotton wool and shape it into a ball. We'll then wrap the cotton ball in a thin wire, creating a frame to hold its shape. Next, we'll soak the cotton ball in hand sanitizer, which contains a high percentage of alcohol.

Now comes the exciting part – we'll light the saturated cotton ball on fire. Normally, fire would quickly consume the cotton, leaving nothing behind. However, thanks to the alcohol in the hand sanitizer, the flame will actually remain cool and safe to touch for a short period of time.

Experimenting with the Freezing Fireball

Once the cotton ball is lit, we'll have a brief window of opportunity to handle the fireball. The alcohol in the hand sanitizer creates a flame that is relatively cool and safe to touch – for a short time, at least. It's important to note that this experiment should only be attempted with adult supervision, as even a cool flame can still cause burns if handled improperly. But when done correctly, it creates a stunning visual effect that combines the elements of fire and cold in a mesmerizing way.

Experiment 8: Erupting Volcano

For our final and most anticipated experiment, we'll be creating an erupting volcano. This experiment requires a bit more preparation and materials, but the results are sure to impress.

To begin, we'll need some modeling clay, baking soda, vinegar, food coloring, and a plastic tarp to protect the work area. We'll use the modeling clay to sculpt a volcano shape, creating a crater in the center where we can add our ingredients.

Once our volcano is shaped, we'll add five doses of baking soda to the crater, using a measuring cup to ensure we have the right amount. Next, we'll mix together 20 milliliters of vinegar and a few drops of red food coloring in a separate container.

Now comes the exciting part – using a syringe or small funnel, we'll carefully inject the vinegar and food coloring mixture into the volcano's crater, right on top of the baking soda. The chemical reaction between the baking soda and vinegar will create a spectacular eruption of colored foam, simulating the dramatic display of a real volcano.

Witnessing the Erupting Volcano

As we inject the vinegar mixture into the volcano's crater, we'll see an immediate reaction. The baking soda and vinegar will start to fizz and bubble, creating a colorful foam that will rise up and out of the volcano's crater, simulating a real volcanic eruption. While the eruption might not be as dramatic as some might expect, it's still a fun and visually impressive experiment that demonstrates the power of chemical reactions. It's a great way to bring science to life in a hands-on and engaging way.
