Potions

From TS3wiki

Sims can create a variety of potions and increase their Logic skill using the Catalyst Chemistry Lab Station. Your Sim can research formulas for new potions using Discover Potion. Sims can then make that Potion whenever they like using the Lab Station. Anytime a Sim makes or discovers a potion, it can be found in the Sims inventory.

Sims who are adept in the Logic Skill can Mix Potions into Drinks. This creates a Mysterious Drink that looks like a glass of water, but causes any Sim who drinks it to undergo the same effects as the mixed in Potion. Leave a Mysterious Drink on the counter or put it in the fridge and watch as other Sims unknowingly ingest the potion. Hijinks are sure to ensue!

One a Sim has discovered all 10 potions they achieve the Master Chemist Skill Challenge in the Logic Skill Journal. This allows Sims to make potions at a 25% cost reduction.
