Gellan is a popular gelling agent and comes in two varieties, high acyl or low acyl. High acyl gellan typically results in soft, elastic gels while low acyl gellan creates hard, brittle gels. They are often used together to create a variety of textures. They can also be used in spherification.
A gel is any liquid (usually) or gaseous medium suspended in a solid three-dimensional mesh which entraps the medium so that it does not flow. By way of (somewhat flawed analogy) think of a giant role of bubble wrap. Its mostly air. But the plastic keeps the air from flowing at a large scale.
