There's a great video from Don Pettit on the ISS where he used candy corn to demonstrate the polar / nonpolar nature of soap. He coated one end of the candy corn with a hydrophobic substance and water as his lipid stand-in. Then he demonstrated how a couple of them would just float on the lipids, but a bunch of them would bind the lipids up and make them water soluble.
It was difficult to grok on the first couple watches because water was taking the role of lipids and air was taking the role of water, but a fascinating and visceral demonstration.
