If you poke a hole through popcorn kernel will it pop more quickly?

Poking a hole through a popcorn kernel will not make it pop more quickly. In fact, it will likely prevent the kernel from popping altogether.

When heat is applied to a popcorn kernel, the moisture inside the kernel turns to steam. This steam builds up pressure and eventually causes the kernel to rupture and "pop."

If you poke a hole in kernel, the steam can escape from hole and pressure will not build up. As a result, the kernel will not pop properly.
