We study about many minerals and chemical substances in the subject of Chemistry. Chemicals which we used in the Laboratory are actually extract from these kind of chemicals. Here I posted also a detailed information of these chemicals as well.
Stalactites and Stalagmites
Much more interesting to see in caves than the laboratory though! We have many caves here in UK and I love getting inside them whenever i have spare time here are a few from my latest cave trip in Derbyshire, UK :)
