                                                        Water-Powered Light Generator

                      Let’s create a Water-Powered Light Generator that uses flowing water to spin a turbine and light up a bulb.
                      Materials Required:
                         Cardboard base, glue gun            2 ice cream sticks (or wooden sticks)      DC motor, bulb

                         Bottle caps, straw                  Small water pump                           Battery
                         Switch, connecting wires            Plastic container (for water)
                      The steps to create the Water-Powered Light Generator are:

                        STEP - 1     Attach a stick vertically to the cardboard and fix the bulb to the top.

                        STEP - 2    Make a hole in a bottle cap and fit it onto the spindle of the DC
                                    motor.

                                               STEP - 3    Glue the DC motor  onto  another stick and fix it  upright  on the
                                                           cardboard base.

                                               STEP - 4    Paste the bottle caps or fins around the cap attached to the DC
                                                           motor spindle to form the turbine.

                        STEP - 5    Fix the plastic container to the base and place the water pump
                                    inside.

                        STEP - 6    Attach a straw to the outlet of the water pump.

                                               STEP - 7    Connect  the battery,  switch  and water pump  using  wires to
                                                           complete the electrical circuit.

                                               STEP - 8    Connect the DC motor wires to the bulb.

                                               STEP - 9    Fill the container partially with water and
                                                           turn ON the switch.

                      When the water flows from the pump through the straw, it hits the turbine and
                      makes it spin. As the turbine rotates, the DC motor converts this mechanical
                      energy into electrical energy, powering the bulb.
