Demonstrations What is plasma? Lightening Plasma novelty light Hear the KTM Bouncy balls in the water jug The more energy, the more the molecules bounces around Never silent because they’re always moving Diffusion food coloring in hot water v. cold water Expansion Gas – balloon in flask Solid – ball through ring Solids – bi-metallic strip bending
