Step 1 – make a hole in the centre of the bottle lid<\/h1>\n
Using a small screwdriver of a sharp object, make hole in the centre of the lid.<\/p>\n
The size should be small, exact size to fit the motor axle.<\/p>\n
If the hole is larger, the water will flow and flood the bottle.<\/p>\n

Step 2 – Glue the motor to the lid<\/h1>\n
be sure you do not glue the motor axle so that it moves freely when battery is connected<\/p>\n

Step 3 – Connect the battery to the motor<\/h1>\n
Using a rubber band attach the wires to each end of the battery<\/p>\n
Attach the wires to the motor pins (just bend into the small holes of the pins or you can even solder if you have a soldering iron)<\/p>\n

Step 4 – Make the propeller using a can<\/h1>\n
draw with a marker the shape of the propeller on the tin and cut with strong scissors<\/p>\n
ATTENTION cutting the tin will create sharp edges and small sharp pieces, be very careful to flatten out all sharp edges (you can use a nail file)<\/p>\n

Step 5 – make a hole in the propeller (same as the one in the lid)<\/h1>\n
attach the propeller on the motor axle on the outside and put a little hot glue to make it stick strongly on the axle.<\/p>\n
Step 6 – attach all wires, insert the battery and mount the lid strongly on the bottle<\/h1>\n
ATTENTION – if the propeller has sharp edges touching the edges when motor is active can harm your fingers.<\/span><\/p>\n
