Answer 2

The item being described is a straw filled with dried peas, which is a model for fluid flow or the principle of action-reaction.

Step-by-step explanation:

In this question, the item being described is a straw filled with dried peas. When a pea is pushed in at one end of the straw, a different pea comes out of the other end. This demonstration is a model for fluid flow or the principle of action-reaction.

In the model, the pea represents a fluid particle and the straw represents a channel or pipe. When a pea is pushed in, it displaces the pea in front of it, causing it to move out of the straw. This demonstrates how fluids can flow through channels and the principle of action-reaction.
