Teachers can make the explaining process much more straightforward and students can better understand its principle.
Run freely on the top of a cup of hot water, no need to fire an alcohol lamp, safer for children.
The start temperature difference between the product bottom contact and circumstance shoulder be greater than 25℃.
Gently flip the wheel, then it can run itself.
