I agree. If you heat up a cup of water or any liquid for that matter and take it out of the microwave, you will notice condensation. Leave the door open to evaporate completely before putting anything like most grains/rice. It will cook a bit.

I was pleased with the result, but I'm not sure I want to give up those big feed corn kernels that stay warm so long.
Anyhow, my thoughts on your puffy rice is this: When I heat a corn bag in the microwave there is a good amount of moisture produced and left on the microwave inner surfaces. Especially with the newest corn bags. I am wondering if the rice in question that puffed up was heated after the others when there was moisture condensation in the microwave and this is what caused the rice to swell.
