Bubbles + Dry Ice (the solid form of carbon dioxide) come together in this step by step video for “creating planets.” It’s also a great DIY parent-kid project for learning about physics, gasses, surface tension, sublimation (when a solid turns into a gas without passing through a liquid phase), and — since dry ice will burn skin — how to safely conduct an experiment!
DIY: A dry ice and bubbles tutorial + how to handle dry ice safely.
