How to play
- Tap bottles on the shelf to add them to the beaker, up to four at a time.
- When two of them react, watch the beaker and hear the reaction played as music.
- Tap Heat to warm the beaker; some mixtures only react when heated, and some salts color the flame.
- Each new reaction joins the Codex; find 3 to open the School lab shelf and 10 for the Advanced lab.
Controls

Tips
- Some reactions take two steps: mix Iron oxide with Aluminium powder, then tap Heat.
- Heat a salt such as Table salt on its own to see a colored flame test.
- Most of what a reaction makes stays in the beaker, so try adding another bottle afterwards.
- Tap a ? ? ? entry in the Codex to get a hint for a reaction you haven't found.
