Chemistry Experiment Lab — RPG Maker MZ Plugin

Pour it. Titrate it. Don't blow it up.

Chemistry Experiment Lab drops eight hands-on chemistry practicals into your RPG Maker MZ game, played like a lab simulator. Your hand shakes a little. Liquids slosh. Pour too fast and acid hits the bench; overshoot an endpoint and the flask turns magenta; heat a sealed apparatus and the bung blows out. Every run is graded, and every result is real chemistry.

No images or extra audio needed — every flask, flame and crystal is drawn by the plugin itself.

The 8 experiments

Level	Experiment	What the player does
★	Flame Test Identification	Light a Bunsen, clean a nichrome loop, identify metal ions by flame colour
★	Paper Chromatography	Match a ransom note's ink to a suspect's pen, then calculate an Rf value
★★	Acid–Base Titration	Rinse, fill and de-bubble a burette, pipette, swirl, stop on the first pale pink
★★	Electrolysis of Water	Pick the right electrolyte, run a Hofmann voltameter, pop and relight splints
★★	Copper Sulfate Crystals	Excess base, filter, find the crystallisation point, grow blue crystals
★★	Distilling Salt Water	Spot the technician's set-up mistakes, distil, prove purity with silver nitrate
★★★	Rates of Reaction	Run a fair test with marble chips, HCl and a gas syringe; read your own graph
★★★	Identify the Unknown Salt	Cation and anion tests on one of 14 random unknown salts

How every lab plays

1. Brief — the objective, the equation, the equipment and a real-world link.
2. Gear Up — choose your PPE and read the GHS hazard pictograms on the stock bottle.
3. Procedure — the hands-on simulation, with a step clipboard.
4. Analysis — questions built from the player's own data: their titre, their gas volumes, their Rf.
5. Lab Report — an animated, stamped grade (S to F), a technique checklist and handbook unlocks.

Score = Technique 50% + Analysis 30% + Safety 20%. Drop the safety rating to zero and the supervisor shuts the lab down.

Realistic, and it shows

• Phenolphthalein's colour follows the actual pH of the flask, calculated drop by drop.
• Electrolysis gives a 2 : 1 hydrogen-to-oxygen volume ratio — and chlorine if you pick salt water.
• Crystal size depends on how fast you cool the basin; boil it dry and they turn white.
• Distillation without boiling chips bumps; a sealed apparatus builds pressure until something gives.
• 33 Lab Handbook pages on techniques, reagents and concepts unlock as labs are completed.

Built for players

• Aim assist: a held tool shows a target ring at its working end, and the places you can pour or set it down glow (Easy and Normal).
• Hover any item to see its name.
• Mouse, touch, keyboard or gamepad — the whole lab is playable without a mouse.
• Three difficulties change hand tremor, tolerances, sample counts, hints and question count.
• Supervisor hints on Normal/Hard (they cost a few technique points), plus a Steady-hands assist.

Built for developers

• Drop-in: copy one .js file, turn it on, call one plugin command.
• Score to a variable, grade letter to a variable, pass/fail to a switch — the event waits for the result.
• Free or sequential progression, plus Lock/Unlock Experiments commands.
• Optional common event after every lab.
• Best grade saved per difficulty in the save file.
• Script calls: ChemLab.start, ChemLab.best, ChemLab.passed, ChemLab.lastResult and more.
• Add your own experiments and wall decor through a documented API.

Setup

1. Copy Chem_ExperimentLab.js into your project's js/plugins folder.
2. Open the Plugin Manager, add Chem_ExperimentLab and turn it ON.
3. In any event: Plugin Command → Chem_ExperimentLab → Open Menu (Lab Cabinet).

Plugin commands

• Open Menu (Lab Cabinet) — all experiments or a chosen subset, optional fixed difficulty
• Start Experiment — run one lab directly from an event
• Open Lab Handbook
• Lock / Unlock Experiments
• Unlock All Handbook Entries / Reset Lab Records

Requirements

• RPG Maker MZ
• Designed for 816×624; other resolutions are scaled to fit
• No other plugins, images or audio required (sound effects use the default RTP)

Terms of use

• Use it in commercial and non-commercial RPG Maker MZ projects.
• Credit appreciated: "Chemistry Experiment Lab by RPG Maker Plugins."
• Don't resell or redistribute the plugin file itself.

Procedures follow standard school-lab practice. It's a game, not a substitute for supervised lab training.
