Just a very trivial question. If anyone knows about this stone ? I found it at a beach. It is quite light. It could be natural purmice stone which floats in, or it could be man-made, called Aerated concete. I've seen words on these stones sometimes ! but this stone has no words. Can aerated concrete be found readily in Singapore, like construction shop ? or any place to find a cheap source of purmice ? The closest to this is lavarock ? lava rock seems quite expensive.
Lol! I use to go to tide pools when I was young to find crabs! I called it crab hunting and I do it with my friends seeing who would get the biggest crab would win! Good times.
