Introduction: Torch in a Bottle

Picture of Torch in a Bottle

I am a recycling geek. So just added a simple bulb from a old torchlight and a plastic bottle. The switch is made from copper tape, so when I make contact from bottle top (funnel) to bottom then buld lights up.

Step 1: Materials Needed

You need 1 plastic bottle any size. 2x1.5V batteries and a battery holder for it. About 20 mm copper tape sold at hobby shops. Some thick foamy doulbe sided type. 1x2.2V bulb salvaged from a old torchlight. 1x bulb holder(can be screw in or twist in depending on bulb type). About 50-100mm insulated wire depending on bottle size. Soldering Iron and solder.

Step 2: Step 1

Picture of Step 1

Cut a soda plastic bottle using a cutter about 1/4 way from cap. Cut all around. Later can use scissors to trim any uneven edges.

Step 3: Bottle Cut

This is how the top half and bottom half contact to on the light something like a touch switch.

Step 4: Making the Bulb Hole

Using an old soldering iron, I made a hole on the cap at the centre about the side of bulb and pushed bulb in.

Step 5: Battery

Attach battery to the bottom half

Step 6: Joining Up the Contact Switch

Now solder some wires to the 2 end of bulb. The two free ends should each be soldered to a copper tape pasted at the edge of the bottom half of bottle. This forms a closed loop (see photos)

Step 7: Completed Torch

Photo shows completed bottle torch. Now all you need to do is wrap a rubber band over wires on top half so it sits nicely into the bottom half. Once the two halves copper tape comes in contact the torch is activated.

you should add aluminum foil around the bulb housing in order to focus the light like a regular torch.

Definately.

That, or really shiny spray paint (the metallic stuff).
