So my science teacher placed a ball into fabric, then i said "The Ball represents the sun while the fabric represents gravity, as the fabric is bending or whats called gravity, it makes whats called a gravitational pull." Then i did a demonstration of the orbit and said "You see that the ball is revolving around the sun? That makes the orbit, and how its faster to the center because its way deeper and once the orbit gets slower, it goes into the sun."
