      I love this question! Individual molecules of water are actually very sticky and stretchy. They prefer to be ‘stuck’ to another molecule of water than anything else. When you wobble a glass of water, what you’re doing at a molecular level (not even microscopes can see this, it’s very very tiny) is trying to separate the water molecules apart. And they don’t like that! So the ‘wobble’ is actually a miny battle between you, trying to separate them, and them trying to stay together. Great question! 🙂
