a: Carbohydrate ~
b: train

What: "After they have done this, I talk about how a carbohydrate is like a train, a string of monosaccharides. When I added water, the train broke up. When the water was taken away, the 'train' reformed. I go over the derivation of the terms, hydrolysis and dehydration synthesis. Students tell me that this demonstration is one of the things they remember most years later." If your teaching basic biochemistry, the link describes techniques for illustrating some basic yet hard grasp ideas about carbohydrate digestion.
