1. Check the air tightness and whether the glass is broken:

Turn the big wheel, with resilience force means normal.
2. Light the lamp, preheat the tube for about 30s (very important), turn the big wheel, and the engine starts working.

Note:
1. Size and color may be slightly different due to manual measurement and different light conditions. Thanks for understanding.
2. Kids should be accompanied by adult.
3. Recommend using (not included) with 95% purity.
4. HOT! HOT! HOT! Don't touch the glass when using.
5. Be careful of the 's spitting out, it's very dangerous. If spitted out, don't be panic; use a wet rag to cover the fire.
