pumice


What is Pumice? Pumice is a type of rock that forms when lava hits water. There is no time for crystallisation and that's why pumice floats on water.

How does it form from volcanoes? The holes are actually gas bubbles that were trapped in the rock during the rapid cooling of a gas-rich frothy magma. The material cools so quickly that atoms in the melt are not able to arrange themselves into a crystalline structure.

What are its properties? Pumice, called pumice in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough textured volcanic glass, which may or may not contain crystals. It is typically light coloured.

How is it like Hockey Pokey? It is like Hockey Pokey because it cools quickly and the bubbles inside the hockey pokey are like the bubbles trapped inside the rock

How did we make it, and get it foamy? We made the Hockey Pokey foamy by adding a teaspoon of baking soda.
