Contest:Your device creates wind
How can you put a wind turbine in to movement so that it generates a lot of wind?

Manual activation: wind and unwind the thread manually or with a weight.
A tube around the rotor guides the air flow better.
Can you find other ways to produce wind?
Contest:
Candle in the middle of the cardboard box
