Advice
- Do you want the flashlight to look more unique? Draw a picture on a piece of paper and stick it around the toilet paper/cardboard tube. For example, the face of a demon. Or, you can glue one end of a paper tube with paper tape and draw a shape on it.
- If the light does not light up, try the following check:
- Did the light bulb burn out?
- Is that a 2.2 volt bulb?
- Are the parts connected to each other?
- Does the battery still have power?
- Is the battery inserted in the correct position?
Warning
- Be careful as the power cord can get quite hot.
- Children should only do this activity with adult supervision
