We really need the mythbusters back :(

I was curious so I did a little bit of research(as in duckduckgo was useless so I asked chatgpt). While stomach acid loses its acidity fairly quickly after death how quickly it happens depends on various environmental factors. Regardless, popcorn kernels apparently pop between 175-200°C(400F). But bodies are cremated between 760-982°C(1400-1800F). So depending on how quickly those temperatures are reached it’s probably more likely that any remaining kernels would just burn.

There’s a chance though. We need some practical experiments.
