Hello everyone!

As the title suggests, I have a question or two about the infamous marshmallow trick that I’m hoping to maybe get some answers to.

First question: I recently came across some marshmallows in my cupboard, which is what inspired me to finally get around to trying this for the first time. However, the marshmallows are preeeetty stale. On the plus side, I think that will make it considerably easier come insertion time. But I’m wondering if the fact that they’re stale will affect how quickly/effectively they break down once inside me. So, is there anybody a little more science-minded than myself or anyone with experience using stale marshmallows that could weigh in? Many thanks in advance.

My second question is more straightforward: how long can I expect the effects to last? I’m only going to be using two jumbo marshmallows (partly because that’s all I have and partly because I don’t want to get myself in over my head). So should I expect the usual cramping and then one big mess after 20/30 minutes? Or a sizable mess within the same timeframe and then some little ones afterwards? Just curious to know for... general planning purposes.

Thanks for reading and for any help anyone can provide!
