In this tutorial are two methods, the first being a command and the second being a brewing guide.
To stop both of these methods either do the command /effect (player name) clear or drink a Milk Bucket.



1. Command
To turn it on:
/effect (player name) invisibility 99999 255 true
To turn it off:
/effect (player name) clear
In the spot where it says Player Name that where you put the desired name, it could be yours or someone else's username.




2. Brewing

Ingredients:





Step 1:

Firstly, make sure you always have Blaze Powder in the top left of the Brewing Stand, then put a Water Bottle in any of the bottom three sections - add a Nether Wart to the top and wait for it to make an Awkward Potion.





Step 2:

Secondly, you will want to put the Awkward Potion in any of the bottom three sections - add a Golden Carrot to the top and wait for it to make a Night Vision Potion.





Step 3:

Thirdly, you will want to put the Night Vision Potion in any of the bottom three sections - add a Fermented Spider Eye to the top and wait for it to make an Invisibility Potion (Which will be 3 Minutes long).




Step 4:

Finally, you will want to put the Invisibility Potion in any of the bottom three sections - add a Redstone Dust to the top and wait for it to make an Invisibility Potion (Which will be 8 Minutes long).
