What You Will Need -
1 AA battery ( some AAA batteries will work )
1 Mini Lightbulb ( light bulbs used for most flashlights; refer to picture)
Ruler ( if needed )
Step 1: Measure Tin Foil
First, you will need atleast about 4 inches of tin foil.
Try to make it as neat as possible.
It should look like the second image when completed.
Step 2: Rolling the Battery in Tin Foil
It's very simple, just wrap the battery in tin foil ( positive (+) side down, negative (-) side up)
(refer to images for help.)
(caution: be aware the battery will heat up in the process in which you are wrapping it. Make sure the battery is securely wrapped or it WILL com bust.)
if the tin foil is too big, trim it, just make sure there is enough for the light bulb to touch.
Step 3: Insert Light Bulb
Make sure the light bulb touches BOTH!, tin foil and negative (-) side of the battery!
refer to images if necessary.
And that's it guys, 3 easy steps to make a light/flashlight
