grated vegetables or liver.

The Chemistry Book memo in Silent Hill 3 explains how to create oxygen using Oxydol, grated vegetables, or liver. Essential for the 'Flame Purifies All' puzzle.

Hey there! So, you've stumbled upon the Chemistry Book in Silent Hill 3, huh? Don't worry, it's not as complicated as it sounds. This little memo is actually a clue for the "Flame Purifies All" puzzle in the Gallery of Fine Arts. You'll find it in the Green Ridge Mental Health Clinic, right after your first chat with Vincent Smith. Just a heads-up, though: this memo only shows up if you're playing on Easy or Normal riddle difficulty. On Hard, it's nowhere to be found. Here's what it says: Easy difficulty: "When you pour diluted hydrogen peroxide onto manganese dioxide, oxygen is produced. Although oxygen will not burn on its own, it will help other things to burn. Oxygen is also formed when the disinfectant Oxydol is poured onto grated vegetables or liver." Normal difficulty: "When you pour diluted hydrogen peroxide onto manganese dioxide, oxygen is produced. Although oxygen will not burn on its own, it will help other things to burn." See? It's all about creating oxygen. The Easy version gives you the full hint about using Oxydol with grated vegetables or liver to get that oxygen. Keep this in mind as you progress!
