How does it form from volcanoes? When lava cools quickly in water the gas bubbles get trapped as the lava soldifies.
What are its properties? Composition- Very thin translucent bubble walls/ Density- Very light weight due to air bubbles/ Buoyancy- Since they are light weight they will usually float in water/ Abrasivity- They are abrasive which is why they are so good at removing dry skin off feet/ Color- Commonly pale in color ranging from white, cream, blue or grey to green, brown and black.
How is it similar to hokey pokey? When out of heat they both cool rapidly and harden very fast trapping air bubbles in the process.
