- MrLeap 2y agoYou'd need to move the laser and keep the disc stationary I wager, otherwise is it even chocolate anymore if it can stand the forces?
- Felomo 2y agoA vinyl is doable. A CD probably not. The refraction doesn't need to be aligned etc. Putting it on and scanning it perhaps but not a one try it life
- perlgeek 2y agoI like your way of thinking :-) A CD as a reflective coating to distinguish the pits, I don't know if that's mandatory though. Very thin gold foil is edible though (it just passes through the intestines, being chemically inert), so maybe a sugar disc coated with gold could be made to be playable, and still be edible? As for the base material, I'm pretty sure that sugar has the better mechanical properties compared to chocolate. If you get it perfectly round and spin it up slowly, there shouldn't be too large forces acting upon it.
