В чашке кипяток, смотри, не обожгись.

Questions & Answers about В чашке кипяток, смотри, не обожгись.

Why do we use the perfective verb обожгись after не? I thought negative commands used imperfective verbs!
You are right that regular negative commands (like "don't open the window") take the imperfective aspect. However, this sentence is a warning about an accidental action, not a command to stop doing something on purpose. For warnings against accidents (falling, forgetting, burning yourself), Russian uses the perfective aspect, usually introduced by смотри, не (watch out, don't).
The lesson mentions using the perfective future for warnings. Is обожгись in the future tense?
No, обожгись is actually the perfective imperative. Warnings with смотри, не can use either the perfective future (like смотри, не обожжёшься) or the perfective imperative (смотри, не обожгись). Both are extremely common and mean exactly the same thing in this context.
Why doesn't the first part say В чашке есть кипяток?
When you are describing the state of a specific location or when the presence of the object is obvious, есть (is/there is) is normally left out. The focus here is on warning the person about the specific cup they are holding or looking at, so the verb is dropped to make it punchy and direct.
What is the infinitive of обожгись and why does it look so different?
The infinitive is обжечься (to burn oneself). It is formed from the base verb жечь (to burn). Like many verbs ending in -чь, its root changes quite a bit depending on the form. For the imperative, it uses the stem обожг-, followed by the imperative ending -и and the reflexive particle -сь.
