This cute little self-contained lamp works like a charm — set it right side up to turn the light on, flip it upside down to turn it off again. I call it the draailampje — that’s Dutch for “flip light.”

While most jars will work, I find a small, hexagonal jar to be particularly pretty. My first containers were mini jam jars from a hotel. Now I use 47mm hexagonal jars, which I buy in bulk.

Making a flip light is easy and fun — great for nontechnical people or first-time solderers, it makes for a perfect workshop or classroom activity.
