In the "Bill Nye the Science Guy" episode on energy, two notable experiments include the demonstration of potential and kinetic energy using a pendulum, where Bill illustrates how energy transforms as the pendulum swings. Another experiment involves using a simple solar oven made from a Pizza box to show how sunlight can be harnessed to cook food, highlighting the conversion of solar energy into thermal energy.
