The Magic Len: A Key Element in the Harry Pattern Universe

By admin

Harry Pattern was an ordinary boy living in a small town called Magicville. Despite his ordinary appearance, Harry had a unique talent for creating intricate and mesmerizing patterns. From a young age, he would spend hours doodling and experimenting with different shapes and lines. One day, while exploring his grandfather's attic, Harry stumbled upon a dusty old book with the title "The Magic Len." Intrigued, he opened the book and discovered that it contained a collection of ancient patterns and symbols. The book explained that these patterns had magical properties and could be used for various purposes, such as warding off evil spirits or bringing good luck.

Yet for all their cleverness, Ravenclaws are consistently relegated to a secondary role in the narrative, augmenting the other houses from time to time with quirky supporting characters and presumably wondering why people don t take them more seriously.

The book explained that these patterns had magical properties and could be used for various purposes, such as warding off evil spirits or bringing good luck. Excited by this newfound treasure, Harry decided to experiment with the patterns in the book. He would copy them onto pieces of paper and rearrange them, creating his own unique variations.

Harry Potter Potions Class – Part 1

Take your Harry Potter party to the next level with a Harry Potter Potions Class full of fun experiments even Professor Snape would approve of.


I am finally sharing our EPIC Harry Potter Birthday Party POTIONS CLASS!

This potions class was one of my absolute favorite things about this party.

I was definitely able to let my inner science geek out in full and led the class as head professor.

I have 8 fun potion ideas for you, including a printable experiment list so you can easily perform these yourself, as well as breakdowns below of each experiment.

Most of the ingredients you need for these experiments you will already have on hand, but some will be specialty items though not hard to find – I even gathered some links for you.

The 8 experiments we did were:

  • Troll Toothpaste
  • Troll Bogeys
  • Secret Messages
  • Miniature Rain Clouds
  • Magic Water Drops
  • Dancing Water Drops
  • Fire Snake
  • And the SUPER popular Hogwarts House Sorting Potion

IN THIS POST I am sharing the first four experiments.

Click each experiment above to go directly to the experiment in the post.


Every Harry Potter Potions Class NEEDS cool potion bottles!

The potions themselves were one of my favorite parts of the class.

You should have seen my little witch and wizard’s faces when I called out the ingredients we would need for each experiment!

I had all of the experiments coded with these special potions so none of the class knew what we were actually using.

I found most of these bottles at Old Time Pottery when they started setting out Halloween decorations (thank goodness for a September party!).

They also all double as great Halloween decorations.

I used Mod Podge to adhere the labels to the bottles followed by another layer of Mod Podge on top so they would not ruin if they got wet.


I am selling high resolution versions of my potion labels in my Etsy shop.

They perfectly match all of the experiments listed below and come pre-sized, as well as individual JPG files so they can be resized to better fit your potion bottles.

There are 27 labels in total, including 3 water bottle wrappers and food tent labels for your food party table.

The Polyjuice Potion label is now a free download at the end of this post!

The Hogwarts House Sorting Solution label is now a free download on the Potions Class 2 post!

Even if you don’t use them all to do all of the experiments listed below, they are fun to have on hand as party decorations.

Harry Potter Potions Class: Troll Toothpaste


Troll Toothpaste is a fun experiment for the kids to watch, but it needs to be performed by an adult.

The best part about Troll Toothpaste is that once the reaction has occurred, it will be safe for your little witches and wizards to touch it!

And, trust me, they will dive right into it.

I made a quick video tutorial to show you how simple this experiment is!

  • A container with a narrow neck (I highly suggest an Erlenmeyer flask because it is the PERFECT shape for this experiment)
  • A tub to do the experiment in (it will get messy!)
  • Funnel
  • 6% (20 Volume) Hydrogen Peroxide (the high grade beauty salon stuff)
  • Dish soap (NOT antibacterial)
  • Warm water
  • Dry Active Yeast
  • Color changing tablet (optional – but adds a fun color to your toothpaste)

For full directions, print the Potions Class Experiments pages below.

You can see in the video the importance of having some sort of tub for your container to sit in. This gets messy!

When you add the yeast solution with the funnel, be sure to remove the funnel quickly when you are done because the reaction will happen quickly.

It is OKAY for the kids to touch the Troll Toothpaste after the reaction has completed. It will feel foamy and warm.

NOTE #1: Make sure your yeast is fresh and use very warm water (get it fresh from the tap if you can) in order to activate the yeast.

NOTE #2: It is important to use the 6% hydrogen peroxide for the best experiment results. Regular hydrogen peroxide is only 3% and will still work but will be pretty boring. This 6% is worth the investment.

NOTE #3: Be sure to use NON antibacterial dish soap. Antibacterial dish soap will not play well with the dry active yeast.

Harry Potter Potions Class: Troll Bogeys


Troll Bogeys was our second most popular experiment to make in potions class!

Remember when Harry accidentally stuck his wand up the troll’s nose in Harry Potter and the Sorcerer’s Stone?

That’s the level of gross we were going for.

And all it really is? Just your everyday slime recipe!


To make Troll Bogeys you will need:

  • Bowls of some sort for each wizard (these mini cauldrons fit the theme perfectly!)
  • Popsicle sticks to stir with
  • Translucent Green Washable Elmer’s School Glue (the perfect bogey color!)
  • Water
  • Baking Soda
  • Contact lens solution

Download the experiment pages at the end of the post for exact instructions.

NOTE: This is an experiment that can be eyeballed! You DO NOT have to have exact measurements.

I dumped several bottles of glue into a large flask labeled Slug Juice and poured it into each cauldron as the kids were ready to start the experiment.

They were so grossed out.

The more water you use, the runnier the bogeys will be so it’s okay if it’s not exact.

I also kept the contact lens solution in it’s original bottle, slapped a label on it, and just squeezed out approximately the right amount into each cauldron.

If the bogeys stay TOO liquid-y, add more contact lens solution.


You can also use this slime (Troll Bogey) recipe to make some fun colors for background potions like these decorative test tubes.

These labels are included in my Potion Labels listing on Etsy.

Harry Potter Potions Class: Secret Messages


We did wand making then Quidditch prior to potions class so that the kids could use their newly painted magic wands to help make the potions work.

It’s fun for them to use them for this experiment.

As you may have guessed, our secret messages experiment is all about invisible ink!


To make the Secret Messages you will need:

  • Paper of some sort (heavier is better since it will be getting wet) for each wizard/witch
  • Q-tips for each wizard/witch
  • Small cups for each wizard witch
  • Paintbrushes for each wizard/witch
  • Water
  • Baking soda
  • Grape juice concentrate

For this experiment you are going to mix the water and baking soda (print the experiment at the end of the post) so that all of the baking soda dissolves into the water.

If it doesn’t, continue to stir in a bit more water until it does.

You can make this ahead of time and label it as Invisible Ink.

During potions class, pour a small amount of the Invisible ink into small cups and have the wizards and witches drawn a secret picture, a note, or a spell with a Q-tip on a piece of paper.

Allow the messages to dry completely (should only take a few minutes), then pass around the grape juice concentrate for everyone to brush over their invisible ink to reveal their message.

Harry Potter Potions Class: Miniature Rain Clouds


Ah, the magic of making it rain!

It’s actually a spell that you can do when you visit Universal Studios in Orlando so it’s a fun addition to your Potions Class.

This is one of the simpler potions to make and all items used (minus a dropper possibly) you will probably already have at home.


To make Miniature Rain Clouds you will need:

  • A cylindrical container (a vase from the dollar store will work great!)
  • Dropper
  • Water
  • Shaving Cream
  • Blue food coloring

This potion is pretty basic.

The more “rain” you add to the clouds the faster they will pass through into the water.

But it will take a minute for it to happen to be prepared to entertain the kiddos while they wait.

Or have them add the water. That will be even more fun for them!

And they can use their wands and say “Accio rain!” to make the rain appear.

Also, as you may have already realized, these experiments can get MESSY.

Be sure to cover your tabletop with a plastic tablecloth (this stone tablecloth keeps in theme with the party) or some sort of covering.

Harry pattern and the magic len

Little did he know that each pattern he created had its own magical effect. As Harry grew older, his pattern-making skills became more refined. He began to incorporate the patterns into his artwork, creating mesmerizing pieces that seemed to come alive. People from far and wide would come to see his work and be captivated by the beauty and magic that emanated from his patterns. But Harry's talent didn't stop at creating beautiful artwork. He soon discovered that he could use his patterns to influence his surroundings. For example, by drawing a specific pattern on the ground, he could create a protective barrier that would keep unwanted creatures away. As word of Harry's magical patterns spread, he became a legend in the mystical world. People would seek his advice and guidance on how to use patterns for various purposes. Harry became a mentor to young artists and taught them the art of pattern-making. Throughout his life, Harry continued to experiment with patterns, pushing the boundaries of what was possible. He developed new patterns that could heal the sick, bring peace to troubled minds, and even manipulate time and space. Harry Pattern's legacy lives on to this day. Artists and pattern enthusiasts from all over the world study his work and try to unlock the secrets behind his magical patterns. His story serves as a reminder that sometimes, ordinary things can hold extraordinary power, and that a simple doodle can transform into something truly magical..

Reviews for "The Dark Secrets Behind the Magic Len in Harry Pattern's Epic Saga"

1. Mia Williams - 2/5 - I have to say, I was really disappointed with "Harry pattern and the magic len". The storyline felt disjointed and the characters lacked depth. The writing style was also subpar, with grammatical errors and awkward sentence structures throughout. It felt rushed and poorly edited. I was really looking forward to this book, but it fell flat for me.
2. John Davies - 1/5 - I couldn't even finish "Harry pattern and the magic len". The plot was confusing and the writing was just terrible. The dialogue was stilted and the characters were one-dimensional. It felt like the author was trying too hard to emulate other popular fantasy novels, but failing miserably. I was extremely disappointed and would not recommend this book to anyone.
3. Emily Thompson - 2/5 - I found "Harry pattern and the magic len" to be very underwhelming. The pacing was off, with long stretches of dull exposition followed by rushed action scenes. The world-building was lacking, and the magical elements felt arbitrary and poorly explained. Additionally, I found many of the characters to be unlikable and their motivations unclear. Overall, it was a struggle to get through this book.
4. Michael Johnson - 2/5 - "Harry pattern and the magic len" had potential, but it failed to deliver. The writing style was clunky and the dialogue felt forced. The plot meandered and lost my interest multiple times throughout the book. There were also too many convenient coincidences and unexplained plot holes. I was hoping for a captivating and imaginative read, but unfortunately, this book fell short for me.
5. Sarah Thompson - 3/5 - I didn't hate "Harry pattern and the magic len", but it definitely didn't live up to the hype for me. The characters were forgettable and the plot felt predictable. While the magical elements were interesting, they weren't enough to save the overall story. The writing was average, but nothing stood out as exceptional. I wouldn't actively discourage someone from reading it, but I also wouldn't recommend it as a must-read book.
