I wanted to share this fun craft activity for the holidays that I've been doing with my family over the last few years. I came up with these while cutting up some cans trying to make an aluminum version of paper spinners.

There are a variety of shapes that work, but generally bigger+lighter spinners are better. Also incandescent bulbs are the best, but LEDs work too.

They remind me of candle carousels I would see at my grandparents' house during Christmas. Let me know what you think!

This is such a charming project! I’ve been quite taken for years by the “Christmas” decorations that spin using a candle.

I quite like these more - mainly because they could be added onto a lamp that puts off heat, and be kind of a perpetual decoration with subtle motion.

I love your “dad turbine” design, and the flying wing has some magical quality to it.

Thank you so much for sharing!

So cool, thanks for sharing.

We used to do that as children as well: a spiral cutted out of paper on top of a long skewer stuck into a potato. Felt like perpetual motion somehow.

It works if you put it on top of a radiator btw.

These look fun, I'm partial to the dad turbine. Too bad (for something like this) that basically none of my lamps produce much heat these days.

    I've not found any LED bulbs that didn't put out enough heat to work.

This feels like the delightful oddities one would stumble across on the Old Internet. Thank you for sharing!

Do people still use incandescent bulbs in America?

    A generation of under investment in energy production will create all kinds of government backed environmental propaganda. Incandescent bulbs = bad. Fossil fueled AI data centers = economy.

    If there was a true environmental motivation for reducing our electricity usage, our bills wouldn't be 60% network charges, they would be 100% usage based charges.

    Looks like they were only (generally) outlawed for sale in 2023. Though some states were ahead of that.

    They last a long time, though, and I imagine a lot of people are still using their existing bulbs. I can't imagine doing that in CA, where our electricity is expensive, but if you're paying 6c/kWh, I suppose, may as well?

    I hope so.

    Some lampshades call for a point source which LEDs struggle to replicate.

      Wow imagine caring so little about the environment...
