I want to show you such a "quick" jet fan. Thanks to him, you can refresh yourself very quickly on a hot day by directing the air flow towards yourself.
So let's get started!
We will need:
1. A bucket of mayonnaise (eaten mayonnaise - the fan did
).2. Motor (can be pulled out of any toy car).
3. Power for the motor (crown or battery.).
4. Glue (titanium, hot melt, moment, etc.).
Step 1:
Attach the lid from the bucket to the bottom and circle (make sure that the middle of the bottom and the lid match, otherwise your circle will turn out to be uneven).
Step 2:
In the resulting circle, draw another one with a radius less than the first by 1 cm (this is necessary so that our propeller touches the bucket wall with blades and doesn’t work for a long time: wink :).
Cut it with scissors or a penknife.
Step 3:
Cut out the shape of the propeller from the circle (the shape may be arbitrary, but do not make it too narrow otherwise the air flow will be weak)
Step 4:
By heating the ends of the blades with a match or a lighter, slowly bend the edges in opposite directions.
Securely attach the propeller to the motor.
Step 5:
In the bottom of the bucket, make a hole for the motor (this can be done with a knife or melted with a soldering iron (or awl)).
Install the motor with the propeller to the middle and secure.
the end
So our fan is ready, now, so that it blows harder, put "+" to "-", and so that it blows weaker, change the polarity (depends on how you bent the edges of the propeller)
