Step 1: Cut and Assemble the Bottle

Sharpie a circle around the bottle for the cut
Carefully use scissors or knife to cut on the mark
Take the top half of the bottle, place the cut end on a hot iron to smooth out
Now, when the top and bottom half of the bottle is put together, it is tight

Step 2: Assemble the Fan Part 1

Cut off both ends of the can
Use scissors to cut the can into a sheet
Unfold the sheet
Draw a circle just 1cm smaller in radius than the smallest circle on your 2 liter soda bottle

Step 3: Assemble Fan Part 2

Cut out the circle and drill a hole in the middle
Draw straight lines to mark the 8 separate propellors
Assemble the screw by adding the Fan the washer then the nut
Use pliers to bend the propellors downward towards you

Step 4: Attach the Fan to the Motor

Drill a hole inside the screw so the motor tip can be fitted into the screw
Super glue the screw and the motor tip to ensure it's integrity
Drill 2 holes in the bottle cap for wires to pass through when the motor is fitted into the cap (if your motor does not have wires, solder the wire to the motor before this process)
Next, super glue the edges of the motor and fit the cap on

Step 5: Attach the Motor-fan to the Bottle

Drill 2 holes at the bottom of the bottle where the wires of the motor can exit
Place the motor-fan into the bottom of the bottle in the center
Make sure the blades of the fan are at least 1 cm away from the sides
Apply superglue and wait for it to dry

Step 6: Assemble the Filter

Take your metal circular metal wire and your netting
Cut the netting to the size just an inch bigger than the circular wire
Apply superglue onto the wire and wrap the netting into the wire (can add tape around the wire)
Stick on double sided tape in the middle of where the Fan starts and the bottom halve of the bottle starts
Slide in the filter on top of the tape inside the bottle

Step 7: Assemble the Nozzle

Use a blade and cut out a hole in the cap slightly smaller than the hose
Squeeze the hose into the cap leaving room for the threads of the cap to be twisted onto the bottle
Recommended: Use a heat gun on the tip of the hose so it is easier to squeeze into the cap

Step 8: Turn It On

Use at least a 12v battery to power the motor
Make sure the nozzle is flush with the ground but leave a little space for air to be sucked in
Be sure not to squeeze the bottle around the Motor for that the blades of the Fan might scratch the bottle
