    DIY Torch Light – Simple Circuit

    Modified: May 14, 2021 · Published: Oct 17, 2019 by Emma Vanstone · This post may contain affiliate links · 3 Comments

    I can’t take the credit for this one as my 9 year old made it in school last year, but it’s just too good not to have on Science Sparks. I love that it’s more than just a circuit. One of my daughters made a long torch and the other a head torch. Both are made using a simple circuit with a paperclip switch.

    DIY Torch with Switch

    What you need to make a DIY torch with a switch

    Pringles tube and lid

    Card cut into a cone shape with foil over the top

    Small bulb

    Battery

    Battery holder with wires attached

    1 more wire

    Paperclip

    2 split pins

    Double sided tape

    Materials for a DIY Head torch

    Instructions

    Carefully make two small holes in the side of the Pringles tube. These are for the split pins to go through and will form the switch.

    Make sure you have a wire attached to each end of the battery holder and use double sided tape to attach the battery holder to the inside bottom or side of the Pringles tube.

    Push the the end of one wire from the battery holder through one hole and secure with a split pin.

    DIY Torch - split pin switch

    Take the spare wire and push one end of this through the second hole and secure with the second split pin.

    The two wire ends left need to be attached to the bulb.

    You should have a complete circuit apart from the gap between the split pins.

    Place the paperclip over the split pin ends to check the bulb lights when the circuit is complete.

    If it doesn’t work check for loose wires and try again.

    Carefully make a hole through the centre of the card and foil cone and push the bulb through.

    Cut the cone down to size so it fits tightly inside the top of the tube.

    Place the Pringles lid on top to cover the bulb.

    Small DIY torch

    Carefully twist one end of the paperclip around the top split pin. You should be able to turn the bulb on and off by twisting the paperclip so it touches the second pin.

    Pringles Can torches

    Decorate as you wish.

    If you use a long Pringles tube make a door in the middle to attach your circuit.

    To make a head torch attach an elastic band around the Pringles tube.

      Hi!
      Love your ideas and using with a class of 30 8-9 year olds.
      On the DIY simple torch the battery holders ( is it 2 AA batteries that are used?) are way out of our league for purchasing 30 of them.
      Can we make our own battery holders? How?
      OR – if we are using the same type of light bulbs as you are – will one AA battery suffice instead of two?

        Hello, one AA battery will be fine. If you don’t have battery holders you could use a thick elastic band around the battery to fix the wires in place, but it is easier with a holder.

          Thanks for a quick reply, Emma, and the advice. Now I will leave it up to the children to explore and discover – but I have suggestions ready if they get stuck! Brilliant!!!
          PS we had great fun and success following the video instructions on how to make a Harry Potter wand- whizzo!!!
