I'm trying to get as many of my demos on film, either stills or video, as possible. This is a classic demo that I show my grade 10 students because it's got chemical change, indicators, and neutralization reactions happening, all in less than a minute. I do it at the beginning of the year and refer back to it as we introduce acids and bases.
I'm going to try and get a slightly better quality video of this after the other teachers are done with the chemicals. Even though my new camera has sound and everything, you can't really hear the fizzing of the gingerale.
*Not really.
That is most excellent. Nothing like a pleasant Rose followed by milk.
ReplyDeleteThis definitely beats my Rocks -> Smaller Rocks -> Even smaller Rocks -> Dust trick.
That's a great demo.
ReplyDeleteThere's a nice set of videos on various engineer principles available at the link below, you might find them interesting.

Thanks for the link, Donald!
ReplyDeleteJorge: the story I tell as I'm doing it is about my bike tour of southern France. You drink a lot of young rosé there and sometimes it is so young you need to follow it up with milk. Then if you've had too much, you have the gingerale.
ReplyDeleteThis year I got applause.
