Phil builds his human-sized tin foil boat wrong several times before he figures it out; he then gets into a tub full of the main ingredients in diapers.

Newton's third law states that for every action there's an equal and opposite reaction; to prove it works no matter how big or small something is, Phil maxes it out by building an air pressure powered rocket car that he can ride.

Phil creates a catapult out of popsicle sticks to demonstrate elastic energy; he then makes a larger one that can launch pumpkins.

Friction is everywhere; Phil tries to reduce it as much as he can; he builds a leaf-blower powered hover disc that he can ride; he also tries to increase his friction enough so he can climb straight up the walls.

Phil makes a bridge large enough for him to cross with pasta; he also builds with blocks; he makes a strong sandcastle.

Phil attempts to build a platform using magnets so that he can levitate; he creates magnet sculptures.
