Ready for the coolest and most fascinating science experiments you've ever seen?

I'm back and today we're making a bunch of awesome science experiments!

They are all so amazing and magical and the best part is that you can find all the ingredients

So let's put our scientific glasses on and let's get started!

Let's make a mesmerizing and magical galaxy out of milk!

Yup, you heard me right, how mind-blowing is that?

Take some whole milk and pour it onto a plate.

I'm using a pie plate, but any kind will work.

Now grab some food coloring and squeeze it out, making a few color bunches around the plate.

I decided to use blue and purple, because as said - I wanted to make it look like a galaxy.

You can also make a rainbow explosion, by using all the beautiful colors of the rainbow!

To activate our magical galaxy we need to dip a cotton pad or a napkin in some dish soap.

Then place it right in the middle of your plate and let this epic show begin!

The colors will start dancing around, creating gorgeous marbled effect.

Seems like the dish soap is pushing milk towards the outer edge of a plate.

Food coloring wants to have some fun too, so it joins the ride, leaving beautiful colored

To make this look like a real galaxy, lets pour in some silver glitter to represent the stars!

You can even take a couple of q-tips and play with it.

Just one swipe creates such a gorgeous swirly marble effect, how pretty!

I could seriously play and watch these swirls for days!

Let's take our galaxy to another level of epicness – yup that's possible!

I'm going to add in some holographic heart shaped confetti too.

These hearts are so sparkly and beautiful.

Sprinkle them all around your milky galaxy and you are ready to enjoy the sparkliest

But what is the science behind this awesome experiment?

The main job of dish soap is to go after fat and break it down.

Soap chases the fat molecules in milk and tries to dissolve them.

This causes the food coloring to move and mix, creating a beautiful colorful display.

That's why whole milk works the best for this experiment – the fattier the better!

This way the soap has lots of fat molecules to catch, which results in a happier colorful

I've been playing with this magical galaxy for over an hour and the colors just kept

Honey, I put the lunch box in your school bag!

All you need to make cute banana messages is a toothpick!

Make small holes in the banana peel close to each other.

You can write dotted words or make little drawings.

At first these holes will look yellow, but after a minute they will become brown!

If you leave a banana on the counter it will get browny and ripe.

This happens because bananas contain an enzyme called polyphenol oxidase.

This enzyme reacts with oxygen and coats the banana with a sort of rust, which accounts

When making small holes in the banana peel we are in a way speeding up this reaction

– polyphenol oxidase cells burst and mix up with oxygen.

An oxidation reaction happens and the parts where we make holes, turn brown.

But no worries, the banana inside will remain totally intact.

What a cool oxidation experiment and nonetheless amazing DIY life hack!

These banana messages are so adorable and perfect to brighten up your own or your friend's day!

Time to make the most epic and mesmerizing lava lamp experiment.

Fill up your glass or a vase with any kind of oil.

I'm using the cheapest vegetable oil I could find in my supermarket.

Since water has higher density than oil, it will sink to the bottom of the glass.

This already looks so satisfying to watch!

But you guys are not ready for the magic that happens later.

Drip a few drops of food coloring into the glass.

Because of the density, color drops travel through the oil layer until they reach the

Take any kind of fizz tablet and drop it into your glass.

The tablet will immediately sink to the bottom and start releasing small bubbles of carbon

This happens because fizz tablet contains citric acid and baking soda.

When these two ingredients react with water sodium citrate and carbon dioxide gas are formed.

The carbon dioxide gas bubbles start rising to the top and take some of the colored water

The gas escapes into the air when it reaches the top and the colored water is left alone

Since water has a higher density than oil, the little water bubble falls back down.

Anyhow, this lava lamp looks so fascinating and I could literally watch these colored bubbles

When your tablet fizzes away completely, you can simply throw in a new one and enjoy

This experiment is so inexpensive to try but so satisfying to watch!

Well, you owe me ten bucks because check this out!

Another super yummy experiment, which totally works as a delicious dessert is edible glass!

Yup, this thing looks just as glass, but tastes exactly like a lollipop.

Take a mold - I'm using this heart silicone one and spray it with a bit of non stick cooking spray.

Spread it around the mold evenly with a tissue paper.

Place a pot over the heat and pour in 3.5 parts of sugar, 1.5 parts of corn syrup and

Optionally add a drop or two of food coloring.

Even after the mixture starts boiling, you should keep on cooking and stirring it

Your edible glass has to reach the temperature of 150 degree Celsius or 300 Fahrenheit, if
