Having just moved home, I stumbled across some books and such from when I was at High School. I think this was around 1994, when I would have been thirteen coming fourteen, so please don't take the piss too much. The reason I have published it is because having read this site for two days solid, I've found myself reading anything in the context that it's spoof, or in jest, and as such this relatively straight-laced list made me laugh.
1. Sand is made of tiny particles of rock or shell that have been ground down over thousands of years, specified in size between 0.125mm and 2.0mm. These measurements differentiate between that of gravel (larger) or silt and clay (smaller)
2. Months after coming back from your holidays, you can still find sand in your bath when you let the water out - This is because the tiny fragments sit in your pores
3. Sand is used to make glass, pottery, explosives, bricks, mortar, concrete, cement, as an abrasive, to filter water as well as numerous uses in farming such as improved drainage, and ease of cultivation
4. There are more stars in the universe than there are single grains of sand in the whole world
5. A bucket you would take to the beach would typically hold 3,500,000,000 grains of sand!
6. The sand from the coast of Namibia in the Southwest of Africa contains a high concentration of diamond particles!
7. When mined for industrial use, 71% of all imported sand comes from Canada, 11% from the Bahamas, 8% from Mexico, and the remaining 10% from other countries
8. Sand is used in hourglasses, and during the late 1800s to mid 1900s, hourglasses were kept aboard ships for timing one hour, half an hour and eight minutes
9. On an average sunny day on any beach around the equator, sand can reach temperatures of 90degrees Celcius! No wonder it burns your feet!
10. Sand dunes make noises when the wind blows that science cannot explain. Recordings have been made of sand dunes barking, whistling, screaming, humming and even sounding like a frog!
