One of my Christmas gifts this year was a Seek Thermal camera, so I can continue my transformation into Rhett Allain. What’s this for? Why, physics, of course. Such as this video of the operation of the Christmas pyramid my parents picked up in Germany, and had set up at the start of Christmas dinner:
Sadly, the Seek Thermal app doesn’t seem to record audio with the video, so you miss out on SteelyKid’s running commentary about the whole thing… But you can fairly clearly see the plumes of hot air rising up from the candle to push the vanes of the fan. There’s probably a way to estimate the flow rate from the rotation of the fan, but I’m on vacation; feel free to write it up, and send it to Rhett for grading…
Anyway, if you got new toys for one winter solstice holiday or another, I hope they’re shiny.
