The Strange Green Sand That Could Reverse Climate Change

Scientists with the non-profit Project Vesta say their special green sand could help remove a ton of carbon dioxide from the air, helping to reverse climate change. The family of greenish minerals called Olivine will help turn beaches and waves into captured carbon rocks. When waves wash over volcanic rocks such as olivine, the water sets off a tiny chemical reaction on the surface – called “olivine weathering” – and pulls a …

The Wonder of HOLOGRAMS

HOLOGRAMS – STEM Science for budding young scientists. The HOLOGRAM in this video is a 3-dimensional photographic recording of a field of light that is projected by laser beams that ‘bounce’ off each other, quite different from a real image seen by a lens like the human eye. The photographic ‘trick’ records the image that is formed when different coloured laser lights are scattered from an object, and then presents …
