Dearest witches and warlocks,

It’s a good thing you read ** my message** and came quick.

I invited everyone so that together you can brew a magic potion to finally rid of us of this evil dragon.

If you succeed – we promise a great reward.

If you fail – our fates shall be very bad indeed.

(Please write down all your work in a clear and organized manner)

You must save us!

Gratefully yours,

Queen Minerva

Witches and warlocks,

The dragon continues to advance towards us, burning down cities and villages with every step.

Using ** your knowledge **of the beast, you must calculate how to defeat the dragon!

**Dargonah **– how many purple spots does the dragon have on him?

**Gregorias** – What is the temperature of the dragon's mouth when it is enraged?

**Beatrix** – What is the amount of water in the dragon's body?

**Dr Mystera** – How many green spots does the dragon have on him?

**Serpyn** – what is the weight of the dragon's brain?

There is no time, we must help one another, and hurry!

Witches and Warlocks,

The guard from our Northern tower sent word that the dragon is getting very close to the castle gate...and is looking very angry.

Quick! We need your help more than ever!

Witches and Warlocks,

I am pleased that you are so focused and serious about this task.

Dearest Witches and Warlocks,

We are almost running out of time. The dragon has already arrived at the castle walls!

Have you found the Witchcraft Formula that will save the kingdom?

Do you know the answers to the following questions:

- What does the temperature of the cauldron have to be?
- What amount of bat saliva must be added to the cauldron?
- What amount of crocodile tears must be added to the cauldron?
- How much time does the cauldron require to cook and dance around?
- How many times must the magic words 'Abra Cadabra' be repeated?

*** VERY IMPORTANT! ***

The time has come to feed the potion to the dragon!

There is only one suitable type of witch's broom for the type of flight required for fighting a dragon.

Calculate, according to ** this formula**, how many hairs the broom will require to deliver the potion to the dragon's mouth.

**Who will be the first to figure it out?**

[username], we need this crucial number... How many hairs need to be installed on the broom?
