not sure if this is the right section for this topic, but here goes.We all love the kitchen science part of the show, but what are your favourite kitchen science experiments? Either those featured on the show / podcast, or ones you have done yourself?Why not post them here, and let us all enjoy the wonder of experimentation.Just post the items you need, and how to conduct the experiment. Like the kitchen science on the show, please do not post what the final result is. That way we will not lose some of the enjoyment of conducting the experiment.If a member is unsure of his/her results they could always pm the poster.OK, here is a simple on to start thins off.
