Dont worry it is not Voodoo..its physics..aka kinetic.
Turn the empty Soda Cans into a Kinetic Lamp .I´ll show you How
Step 1: The Can.
When the top and the bottom were removed, fill the can with Paper.
Then Sand sand it, paint it , google some image or draw whatever you want., stick the image and start to hole all over the picture you want (I used an Office pin.).Remove the picture or draw and with a sharpie draw the image.and add some details.
Step 2: Motion.
Find the center and divide the circle in eight parts.
Cut the flaps with a cutter, and fold down in 45,00072 degrees.
make a hole in the center and glue a Glass Vial.
Finally , glue the circle on the Soda can.
Step 3: Axis.
We need a piece of wire, a tiny piece of plastic Tube like an empty pen tube, a lighter part (valve), a sharped Needle.
Join together those parts.
and place a light Bulb.
Step 4: Light Up.
Step 5: Its a Kind of Magic...!!!
the inner air..warms and find a way out so goes up and push the Flaps.
Hope you like it rated and vote.
