Phil conducts an experiment in which he makes a chain fly into the air due to the force of gravity. He explains how the experiment works and demonstrates it at a larger scale.

Phil demonstrates the use of mechanical advantage to pull heavy objects with less effort. He acts as a superhero named Mechanical Advantage Using a Force Man to move a car using a rope, mechanical advantage, and his own strength.

Phil conducts an experiment in which he tries to spin a pencil on its tip. He fails initially but is successful after sticking it through a circle of cardboard. He explains why it works and mentions the "smart" way to describe the phenomenom: the conservation of angular momentum.

Phil explains and illustrates Newton's first law of motion and angular momentum using a 20 kg weight. In the experiment, they are having trouble spinning the weight fast enough. They eventually spin it fast enough that it doesn't topple over immediately.

Glaciers appear on almost every continent. However, they are rapidly melting due to the warming climate.
