Safe Lantern
When the cup falls down, It is only the oil inside that spills out. The flame will stay in the cup and would not cause fire.
The oil is durable for long hours: about 5g per 3 hours.
The feature of this lantern is on its safely. As the flammable temperature of a cooking oil is 360 degrees celcius,
it is safe as long as the oil is kept to room temperature, even if the cup falls down.
However, keep in mind to fix the cup stable so that the oil would not come out with aluminum foil.
Make sure to prepare the lantern before blackouts.
It is safer to use a jar with a lid (like a jam jar) to avoid spilling.
You can make the lanterns in 2 to 3 minutes. Please try it.
