I just found out the person who wrote YIFF in my binder... im coming for you Martinez 
To make itching powder, you need:
1)Rose
2)Boiling water----1 Cup
3)Knife
4)toothpick
5)Bowl
6)Sunlight
Get a red rose. Put it in a dark,dry area so it will die quicker.
When a rose dies, a small green round fruit-like formation grows in the middle of it.
Once the rose dies, remove this small fruit-like formation.
Take a knife and cut it into two halves.
There will be cotton like stuff in the two halfs.
Take a toothpick and remove this cotton-like stuff(scientifically, it is called cythilicus).Don't touch it with your bare hands.
Place it in a small cup.
Place this small cup next to the boiling water cup so it can absorb the steam of the boiling water and become fluffier. Don't let any water touch the cotton-like stuff.
Don't place it in the microwave or it won't work. It NEEDS to absorbe the STEAM.
Once it becomes fluffy(after 10-15 minutes next to the boiling water cup), place the cup of cythilicus under the sun.
It will turn down to powder. Place it on someone and have fun laughing at them. It even goes through clothes. PS-This is serious stuff. DO NOT put it on anyone's eys or lips or anywhere internal. It is especially uncomfortable under the arm pits. Do not use on anyone you love, just people you really hate.The itching usually lasts up to 1 hour.
If you live somewhere cold, if you line his coat with it, he'll have a bad day...
