How do I run an experiment?
Open the Lab tab, tap Add substance, pick elements or compounds, switch on equipment such as the burner or water dropper, then tap Mix & React.
Why does it say "No reaction"?
Many combinations really are stable. The card explains why and suggests what to add: heat, water, electricity or a different partner.

Is the chemistry accurate?
