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.

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).
