oh if any mistake forgive and help me correct.
Step 1: The things you will need
the things needed can all be found at house.the things you will need are:
1)plastic or glass jar or cup that are transparent.(must be transparent)
2)aluminium foil small piece is enough.
3)1 paper clip.
4)cardboard piece small one.
6)insulative tape or any tape
firstly take the paper clip and straighten it.if there is any insulation on it remove it using scissors.then bend one end of the paper clip into a shape like 'U'.
now take the cardboard.unscrew the cap of the glass ar if any and then put its opening on the cardboard.using pencil mark the outline of the opening of the jar.now cut it using scissors.
now mark the center of the cardboard circle.using a scissor make a small hole.
now take the piece of aluminium foil and draw a small leave structure with fat as a penny lower end and on the upper end make it thinner.now cut two of these.make a hole at the top of both foils.
Step 6: Now making the collector
now take the remaining aluminium foil and crumble and scrumble it into a nice round shape.
