The "Concoctanation Station"

The "Concoctanation Station" is an item that was added in The Sims: Livin' Large. It allows Sims to create potions of varying effects, but the player cannot select which potion will be made.

Usage
A Sim needs at least one cooking point to be able to use this item. Using this item increases a Sim's logic skill. However, if the Sim using it has a low logic skill, potions being made can easily blow up in the Sim's face, or go drastically wrong, creating a horrible smell that will waft around the neighborhood, causing the police to appear and fine the Sim. Having a full logic skill (10/10) greatly reduces but does not eliminate the possibility of explosions or release of stench. Also, if it is used outdoors during school hours, the police will come and fine the user, even if the potion is made successfully. (They will even come if a Sim drinks a potion during school hours, but only if it's done outdoors.)

If a guest or friend that is in the house drinks any potion in the chemistry set, they will suddenly walk out of the house and cannot be interacted with.

Potions
The potions and their usages are as follows.
 * Blue: Sims are more likely to make this potion than any other. It maxes out three random needs and can be extremely useful.
 * Yellow: This reverses a Sim's personality forever. The reverse works simply on the 10-point scale; a Sim who had had 3 Nice points, now has 7 Nice points and so on. However, changed personality can be reverted back if the Sim makes another yellow potion and drinks it.
 * White: This can cure sickness, although it rarely appears. It will not appear unless the Sim using the chemistry set is sick.
 * Purple: This turns a Sim into a monster for a set amount of time. The monster will wander around the house to use items, which they always end up breaking, especially the television. They also have a tendency of waking up sleeping Sims who are in the same room. If easels are available, the monster will use them and paint the same picture that children paint, but will paint it quicker.
 * Red: This makes the drinker's worst enemy in the neighborhood fall in love with them and appear next to them.
 * Orange: This render the Sim invisible for a space of time (for 12 - 18 hours). Invisible Sims can't do much; they can interact with other Sims, but those Sims can't interact back.
 * Dark Green: This makes a reverse clone of the Sim, which will wander around and eventually disappear. They tend to ruin the Sim's relationships with other people because they think the clone is the original.
 * Light Green: This potion drops all of the Sim's Need bars so that they are almost empty. Should a Sim brew this potion, it is best not to drink it and instead sell the chemistry set and buy a new one.
