FAQs – We’ve Got You Covered

• Q1: What heat source do I need?
  A: Alcohol lamp, small candle, or even hot water works. Alcohol lamp recommended for consistent spinning. Heat source not included.
• Q2: Is it hard to start?
  A: Super easy! Heat the hot end for 10–20 seconds, flick the flywheel gently, and it starts spinning. Instruction sheet included.
• Q3: How long will it run?
  A: Depends on the heat source. A full alcohol lamp (~50ml) runs 30–60 minutes. Swap out or refill for longer runs.
• Q4: Is it safe?
  A: Yes! Hot end gets hot—don’t touch it. Weighted base prevents tipping. Teens 16+ should use with adult supervision.
• Q5: Does it need oiling?
  A: No oil needed—pre-lubricated. Keep shiny by wiping with a dry cloth. Avoid moisture or drops.
• Q6: Can it be used in schools?
  A: Perfect for teaching thermodynamics, energy conversion, and thermal expansion. Way more fun than a textbook!
• Q7: Is it gift-ready?
  A: Absolutely! Comes in a premium box with instruction manual. Heat source not included due to shipping restrictions.
