Perhaps not really a proper “Science Saturday” post, more eye candy if I’m being honest. But this is still fun to watch. YouTuber Brusspup filmed a series of experiments which show the effects of a loud 24Hz sine wave on streams of water, with the camera frame rate adjusted to match the vibration of the air. Brusspup explains:
If you want the water to look like it’s moving backward set the frequency to 23hz. If you want to look like it’s moving forward in slow motion set it to 25hz.
You know you’re gonna want to try this at home too, so he’s very kindly listed in the “About” tab in YouTube all the instructions and things you’ll need to try this in your own back yard.
Honey, where’s me wellies?
