Science Bits: What is Fly Ash? What are its uses?

[@magnifier143]

I was regular viewer of science simplified. Thanks to host and vekanteswar sir. That series helped me a lot to know about modern developments in science. However I liked the previous version more, but okay with this too.. as such short videos may attract more curious people.

Could you please keep the diagram and text visible clearly because sometimes your logo and bottom border cover them? It will help take the screenshots. Thanks.
