Programmable popcorn

Imagine a cup of popocorns that all have the same shape...

This is a material experiment under the context of subtractive manufacturing.  I was inspired by this slow-motion video capturing how corns pop into popcorns. I noticed that the kernel was teared apart by the inner force. The force is so huge that it happened instantly and randomly. So I’m wondering if I can control where the kernel is teared by pre-cutting the kernel before popping. 

Fabrication process:
#1 laser cut corn kernels

#2 Microwave heating

A crossing cut
result in the four leg/pedal shape
