Performing the Experiment

First and foremost, you need to choose an area with lots of space. There’s a reason this experiment is called the elephant toothpaste DIY right?

Once, the area for the experiment has been finalized, it’s time to assemble all the utensils and chemicals at hand.

To start the process, add 3% of hydrogen peroxide to a clear jar or cup. Next, add a few drops of your favorite dish soap, it’s better if the dish soap is of a nice attractive color.

Next, add a few drops of your favorite fragrance. Give the jar/cup a little whisk so that each component is well-immersed with the other. Add a small spoonful of yeast solution.

This solution is made by mixing yeast with water. Now add the diluted version of yeast into the mixture and mix them.

Next, maintain some distance, and you’ll find a colorful bubbly solution coming out of the jar, most probably taking over your table.

#2 Making the Pirhana Solution With Hydrogen Peroxide

Pirhana solution is a good old mixture of concentrated sulfuric acid backed up by some hydrogen peroxide.

Mainly, prihana solution is used as a cleaning substance for organic residues like photoresist from substrates.

Moreover, the same mixture can be used for a non-rigorous safe experiment.

Now when it comes to a simple fun DIY activity with your kids, the mixture of prihana solution with hydrogen peroxide is a great option. Let’s see how that will work.

How it Works — The Principle

Note that piranha solution is a powerful oxidizer and should be used as a last resort when it comes to DIY activities.

The use of pirhana solution should be done with the utmost care and only under expert supervision. The results will for sure blow away the mind of your kid, fascinating them.

However, all of this should be done from a safe, distance, keeping in care that the ingredients need to be of the perfect balance.

What You Need

  • 30 ml. conc. Sulphuric acid
  • 10 ml. 35% hydrogen peroxide
  • Arrange a clear jar
  • A mixing utensil

Performing the Experiment

To start the experiment, grab a weighing counter and place the empty jar on it. Then add a carefully measured 35 ml. concentrated solution of sulphuric acid. Next, add 10 ml. 30% hydrogen peroxide.

Make sure that the amount of hydrogen peroxide doesn’t exceed this. If it does, it could lead to an explosion that’s of course going to be harmful.

The recommended ratio of hydrogen peroxide and sulphuric acid is 3:1. Once, these have been added, wait and let the solution mix.

On to the stage of some experimenting now, first, place a paper into the solution and watch how it burns into the place. Next, have some fun with a cotton ball.

It’s a favorite of the kids out there. The cotton ball once comes in contact with the solution, burns right there and then, and the whole jar is taken over a black color.

Pretty amazing right? You can spend the whole day adding other fun stuff and watch it burn. Kids love this stuff.

#3 Creating a Genie in a Bottle With Hydrogen Peroxide

Producing a genie with hydrogen peroxide seems weird and almost impossible. But it’s far from that and oh such a fun activity for your kids.

The main concept behind this experiment is that oxygen is right there in the air and when it comes into contact with hydrogen peroxide, the chemical tends to break/fall apart.

How it Works — The Principle

Genie in the bottle is a manganese oxide-catalyzed decomposition of hydrogen peroxide. The experiment shouldn’t be done in a volumized flask as that could create some problems.

Moreover, it should be noted that the quantities of the ingredients should be extremely up to the mark and accurate.

You’ll also have to buy manganese dioxide that usually comes in a brown packet l, securely shut, to avoid any exposure to oxygen and the same can be said about hydrogen peroxide.

What You Need

  • Splash proof goggles
  • Gloves
  • Flask/ Small pet bottle
  • 35% hydrogen peroxide
  • Tissue box
  • Manganese dioxide
  • Yarn ball

Performing the Experiment

When it comes to experimenting, first of all, all the safety precautions need to be set in place.

To cover the safety realm, wear gloves, splash-proof goggles in case the solution splatters everywhere, and a white coat for aesthetics.

Once done with all of this, next pour 35% of hydrogen peroxide into a bottle. Next, grab a small piece of tissue add a small quantity of manganese dioxide to it, and secure the tissue.

Cut a long string of yarn and tie it around the tissue. Now, comes the real part of the experiment.

Slowly let the string attached to the tissue into the bottle that already has the hydrogen peroxide mixture in it.

And stand back. In a second or two, you’ll see smoke or the ‘genie’ slowly rise out of the bottle. This can be in the form of smoke or water droplets. Such a sight will for sure leave your kids bewildered.

#4 Start a Fire Without Matches Using Hydrogen Peroxide

Want to do something magical? Start a fire without matches. Seems crazy right? But it’s not for the input of a managed ingredient, such a reaction can be arranged in a few seconds.

And it seems like a fun DIY activity to do with your kids in some leisure time.

How it Works — The Principle

It is no secret that hydrogen peroxide is an oxidizing agent and when combined with glycerin, the mixture can do wonders that can’t be comprehended by the naked eye.

These two components are bound to cause combustion as glycerin is highly susceptible to oxidation. To experiment, the main two components are hydrogen peroxide and potassium permanganate.

Take a look at the detailed list of materials required to experiment.

What You Need

  • Splash free goggles
  • Potassium permanganate
  • White lab coat
  • A clear small bowl
  • 35% hydrogen peroxide
  • Syringe
  • Ceramic plate

Performing the Experiment

Wear your gloves, lab coat, and splash-free goggles to protect yourself. Then grab a small clear bowl, and add a pint of potassium permanganate to it.

Next, grab a syringe and fill it up with 35% hydrogen peroxide, but not up to the brim.

Now, place the bowl onto the ceramic plate and slowly and steadily add the hydrogen peroxide by pressing the syringe into the bowl.

Once the hydrogen peroxide comes into contact with the permanganate, smoke will start rising, a sign of the fire that just burnt before your eyes.

This experiment can be done in an open large flask too, with the same procedure as mentioned earlier.

Once you’re done with the experiment, make sure to open some windows to get rid of the burning smell and after some time has passed don’t forget to wash the bowl that was used in the experiment and run it under lukewarm water to wash away any residue.

#5 Surface Area Experiment With Hydrogen Peroxide and a Potato

Potato-catalyzed H2O2 decomposition is a fun experiment to carry out alongside your kids. It will for sure allow them to learn something new while having fun.

A mixture no parent wants to let go of. Therefore, during the upcoming winter break, go for this experiment.

How it Works — The Principle

Even though it may seem like two components, in this experiment, along with potatoes and hydrogen peroxide, the surface area is also going to be analyzed.

When reacting with each other, these components produce oxygen and water. However, we will be focusing on the oxygen that is to be produced and the output that it brings.

The experiment is harmless and doesn’t require any fancy equipment or ingredients to pull it off. Therefore, it’s a quick, simple, and scientific way of having some fun with your child.

What You Need

  • Knife
  • Potatoe
  • Cutting board
  • A measuring scale
  • Three glass jars
  • 35% hydrogen peroxide

Performing the Experiment

To start the experiment, grab a whole healthy potato and place it on a cutting board. Next, grab a sharp knife and cut the potato into slices, not too thin, and not too thick.

The next step is to take the measuring scale and place it alongside the potato pieces. Using that, you cut off the sides of the potato.

Once that is done you take each piece of potato and start cutting it first horizontally and then vertically. Then grab 3 jars and pour the 35% hydrogen peroxide into each of them.

Now, start filling up the jars with the potato pieces until all the pieces are added. Now, wait and watch as bubbles and foam starts to appear on top of the potatoes.

The main purpose of this experiment was to take a look at how the output of a certain solution changes following the surface area which is given to it.

If you choose a tightly shut utensil with limited space, the potatoes and hydrogen peroxide mixture wouldn’t be able to produce significant oxygen.

#6 The Raw Food Reaction

Raw food and hydrogen peroxide work perfectly with each other resulting in a mind-blowing output.

The reason why raw food and hydrogen peroxide tend to work together is that hydrogen peroxide has poor but relatively poor reactivity making it capable of generating free radicals.

How it Works — The Principle

Raw food contains a substance called catalase and this is a perfect complement to hydrogen peroxide.

The enzyme plays a helpful hand in breaking up hydrogen peroxide and when both the substances, raw food, and hydrogen peroxide are mixed, it leads to a mushy or bubbly solution on top.

A fun experiment right?

However, do remember that this experiment won’t work with cooked veggies or food of any sort as the heat from the stove inactivates the catalase required for food and hydrogen peroxide to work with each other and lead to a reaction.

What You Need

  • 35% hydrogen peroxide
  • Vegetable of your choice
  • Aluminum foil
  • Knife
  • Cutting board

Performing the Experiment

To start this fun journey, grab a cutting board and vegetable of your choice which could be anything.

Next, pick up a sharp knife and cut the vegetable/raw food into small pieces, small enough that they fit into a normal-sized glass jar.

Now fill a quarter of the jar with 35% hydrogen peroxide. Once that is done, top it off with the pieces of vegetables/raw food.

Wait and watch how the top of the vegetables gets covered with bubbles and foam.

It’s certainly something fun to watch and experience with your kids. Once done with the experiment the raw food is no longer fit for use.

Therefore, it should be thrown in the bin and the jar that was used for the experiment should be thoroughly used and cleaned with a brush to make sure no substance from the experiment is left behind.

That’s how you do a fun experiment all while being safe.

#7 Revealing Fingerprints With Hydrogen Peroxide

Want to add a little fun to your experiments? Go for the fingerprint experiment with your kids. Plan out a whole mystery scene with them and make it a whole deal.

And when it comes to catching the culprit, you do it with the help of the genius hydrogen peroxide experiment.

How it Works — The Principle

This experiment will make you and your kid feel like a whole scientist. The theory behind this experiment is that an acidified peroxide is used to uncover latent prints backed up with uncoated brass.

The chemical solution that is prepared reacts perfectly well with the oils that human skin releases while normal functioning. Hence, any hidden fingerprints are revealed.

The experiment is simple and to the point, requiring no input of any fancy equipment. Therefore, it can be carried out within the comfort of your house.

What You Need

  • 35% hydrogen peroxide
  • Distilled white vinegar
  • Gloves
  • A measurement jar

Performing the Experiment

To start the experiment, get a measurement jar. Once done with that add 35% hydrogen peroxide up to 400 ml. Next, grab the bottle of distilled white vinegar and add 1 ml of it.

To test off the experiment place the equipment or material of inspection which could be a ring or even a fake bullet within the jar. Let this material simmer and wait for a total of 12 mins.

Once the 12 mins have passed, use your glove-added hands to grab the material within the jar. Upon inspecting the material under bright light, you’ll see fingerprints all over it.

And that’s how one reveals fingerprints with the help of hydrogen peroxide coupled with a small amount of distilled vinegar.

The experiment is to the point and a fun way to do some mind-bending activities with your kids. A whole crime scene with different kinds of side characters can be set to immerse into the full experience.

Essential Safety Precautions

When it comes to the handling of hydrogen peroxide, it is important to take the necessary precautions. Especially when this peroxide is being handled at home, for fun little experiments.

Even though the concentration that is to be used for the experiments is going to be low, up to 3%, however, some necessary steps are still important.

Here are essential safety precautions for hydrogen peroxide when it comes to its storage and usage:

  • Taking a look at the storage side, hydrogen peroxide should be kept in a cabinet. And each area has different limits when it comes to the storage of oxidizing agents that can be stored in one cabinet.
  • Moreover, the cabinet in which hydrogen peroxide is being stored should be built to ensure that the oxidizing agent is protected from contaminating substances and eliminating the risk of a dangerous reaction.
  • If there are substances that are kept alongside the oxidizing agent, they should be constructed of non-combustible materials.
  • When it comes to use it is recommended that splash goggles are worn, hands are safe with the help of high-quality gloves, and there’s an approved vapor respirator just in case of an emergency.

The Bottom Line

All the experiments mentioned above are entry-level. Therefore, you can try them out in the comfort of your house with kids. As long as you follow the right precautions, you and your kids will be safe around the chemical.

But to do so, you will have to buy a high-quality hydrogen peroxide of the right concentration for the experiments. You see, peroxide might be a common household chemical, but not everyone gets the right one.

To ensure total safety, you need to use the pure thing.
