On a mobile phone it makes a lot more sense. Try shaking it!
It doesn’t in my case, I see some weird animation, everything disappears, “pour” button again. Shaking or any other movement doesn’t help. Latest chrome on iOS
I think it responds to tilting, not shaking?
Maybe it’s too much for my iPhone 13 or something, I can see it but it’s all choppy and slow
The demo runs like a slideshow on my humble budget android phone from 2021
