Potions are advanced things.(not in p.e.) Some potions are strength, swiftness ,poison, and much more. In order to make potions you need to craft a brewing stand. You need 3 cobblestone on the bottom row and a blaze rod in the middle. But In order to make potions you need to make an awkward potion. An awkward potion is the base of the potion. In order to make an awkward potion you need a nether wart (found in the nether) and a water bottle. To make a potion of strength you need blaze powder and an awkward potion. Then you get a strength potion and to make it last longer you need to add redstone dust. To make it a splash potion you need to add gunpowder. To make the potion better, like strength 2, you will need to add glowstone dust.
