I made a turntable cake. Everything is edible (except the tiny speaker embedded in the cake and the rotating mechanism.)

I created a Spotify scan code for this Alanis Morissette album on a sugar sheet and so when it was scanned with a phone, The cake played the album. I know the pin should be on the record when it plays but I didn't have time to figure out the physics there.

And of course, the record spins as well.
