Speak to Parry Pippin and tell him that you would like to help deliver some invisibility potions to another alchemist, Fatimah Lawang in Keenbridge. The village of Keenbridge is on the river well south of Hogwarts, and if you’ve never been there you won’t be able to travel there via Floo Flame. So either hop on your broomstick and fly to Keenbridge, or if you’d rather take it slow and explore a little more en route, make the journey on foot. Talk to Fatimah Lawang at her stall in the middle of the village and she will insist that you drink one of the invisibility potions to prove it works. Tell her, “Of course.”
How to drink an invisibility potion

Hold L1/LB, use the right stick to select the invisibility potions on the inventory wheel, then release L1/LB to close the inventory wheel. You should now see the invisibility potions next to your mini-map. Now just tap L1/LB to drink the potion and briefly turn invisible. Talk to Fatimah Lawang again, then travel all the way back to J. Pippin’s Potions in Hogsmeade and tell Parry Pippin you delivered the potions. This completes the quest “A Challenging Delivery”.
