How to let something spin in water without moving ? Answered
Ok, first ill explain what I have built, and excuse me if it already exists, I can't even think of how to google/name it.
A can floats in water, there is a candle in the can.
On top of the can there is a propeller which is stuck to the can.
The hot air rises and lets the fan (and therefore the whole can) spin.
The power is very little and the can tends to move to a side of the bowl and that friction stops it.
Is there a balance problem ?
Is the not perfect propeller working like a sail and therefore pushing it to the side ?
What could I do to let the can stay perfectly in the middle while spinning ?
Thanks in advance.
