Introduction: Candle Holder With Parabolic Reflector
This candle holder reflector came about from making a candle holder which cast a silhouette:
It could be made brighter by altering the shape of the reflector into a parabolic curve. This remix improves upon the previous design and puts out more light. A prototype is also shown.

Step 1: Cut Out
* Draw the shape shown on an aluminum beverage can with a marker.
* Cut out the shape with the box cutter. Cutting this shape requires care, go slow and for the tight curves, just use the tip of the box cutter to work your way around.
* Cut out the top curve (peak) from the cut off.
* Trim any jagged edges with the scissors.
Step 2: Draw a Parabolic Curve
* using a piece of string and a right angle, (I used the corner of a book) draw a parabolic curve, with the focal point being the centre of the can.

Step 3: Shape the Reflector Into a Parabolic Curve
* Cut a piece of wire from a wire coat hanger.
* Shape it to a parabolic curve, using the
drawn curve as a guide.
* Stick it on the back of the reflector, so it now takes on a parabolic curve. I used glue and packing tape. The uhu glue was replaced with super glue. If using super glue be careful not to glue your fingers.
Step 4: Flatten the Base of the Can
Flatten the base of the can a bit with a hammer.
Step 5: Add on the Peak
Glue on the peak which had previously been cut out.
Step 6: Add in a Candle
Secure the candle with a few drops of wax on the base.
Step 7: Prototype
This prototype, put out a little more light as it had a larger reflector but didn't look as neat.
