In these few pictures I mess around with one of the newer potions, the invisibility potion. To make an invisibility potion you need to make an awkward potion. To do this you need a brewing stand, a glass bottle filled with water, and a Netherwart. Place the Netherwart in the top and the glass bottle with water in one of
the three bottle compartments on the bottom. Then to the awkward potion you add a golden carrot (A carrot which has been crafted with 8 golden nuggets around it in a crafting bench) to the top compartment. That will make a potion for night vision. You can either keep it as it is as a night vision potion, or you can add a fermented spider eye to the potion to make the potion of invisibility. You can also make the potion throw able, by adding gunpowder to the potion. That will make it a splash potion. I used a splash potion of invisibility on the spider, mooshroom (a cow with mushrooms growing on it) and sheep in these pictures.
Other uses beside creeping up on people and scaring them, with the potion in effect, hostile mobs will ignore you unless you are wearing armour, because the armour (and weapons you hold) are still visible.
