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.
