- Do not confuse with a 'lamp shade' (абажур).
Common Mistakes
- Misspelling as 'lava lamp' (two words) is standard, though 'lavalamp' is occasionally seen informally.

FAQ
Frequently Asked Questions
It is standardly written as two separate words: 'lava lamp'. The hyphenated form 'lava-lamp' is sometimes used when functioning as a modifier (e.g., lava-lamp effect).
Modern lava lamps are generally safe when used according to instructions. However, they can become very hot, should not be covered or shaken, and should be kept away from children and pets due to the risk of burns or breakage.
The name is metaphorical. The rising and falling blobs of coloured wax or oil visually resemble the slow, viscous flow of molten lava, hence the evocative name 'lava lamp'.
Simple, non-heated versions can be made as science experiments using water, oil, food colouring, and effervescent tablets (like Alka-Seltzer). However, these are temporary demonstrations and not functional, heated lamps like commercial products.
