Just a word of caution: do not attempt to heat a pop-tart in a microwave for over 2 minutes. Don’t do it. There are other things you can do with those things: like making them light-up and well, eat, I suppose.
For the once that cannot wait to see what happens, eventually those things will smoke like hell. Mine did. And they get hard as a brick too. Imagine seven pop-tart ninja fighters.
