Make+a+Torch

Dark and Stormy Night
Imagine you are driving with Dad in the car on a dark and stormy night. The car breaks down and Dad has to walk to the nearest house, about an hour away. You scratch through the glove-box and behind the car seat and this is what you find:
 * 2 batteries
 * cardboard tube
 * aluminium foil
 * paper clips
 * drawing pins
 * sticky tape
 * copper wires
 * a globe from the overhead light

Can you make a torch, with a switch, that can be turned on and off with one hand? Your torch will be judged on it’s reliability, ease of operation, brightness of beam and sturdiness of the connections.
