BlackAndWhite on Instagram: "Surface tension is a physical phenomenon that occurs due to the cohesive forces between liquid molecules at the surface. In a liquid, molecules attract each other equally in all directions, but those at the surface experience an imbalance—they are pulled inward by neighboring molecules but not outward by the air above. This creates an invisible “film” at the surface that resists external force and minimizes the liquid’s surface area. Surface tension explains why smal

Big Little Farm - Brendan & Caitlin on Instagram: "Burning timber posts is an old-school preservation trick that still works brilliantly today. By charring the wood, you seal the outer layer, making it far more resistant to moisture, insects, and rot once it’s in the ground. The carbonised surface acts like a natural barrier, slowing decay without needing chemicals that can effect your soil. A little fire now means years of extra life for your inground timber. #homesteading #diyprojects #woodwor

Did You Know on Instagram: "Solvent-based paint removers work by breaking down the chemical bonds in paint, allowing it to soften, lift, and separate from the underlying surface. These removers contain strong solvents such as methylene chloride, toluene, acetone, or NMP (N-methyl-2-pyrrolidone), which penetrate the layers of paint and dissolve the binders that hold the pigment together. Once the paint becomes softened or blistered, it can be scraped off easily with a putty knife or similar tool.

Detailed Explanation on Instagram: "Using aluminum foil and a little water to remove rust from chrome works because of a mix of chemistry and gentle abrasion. Aluminum is a softer metal than chrome, so when it rubs against a chrome surface it does not scratch or damage the finish. Instead, it creates a light polishing action that breaks down surface rust without harming the underlying layer. When the foil is dipped in water a mild chemical reaction occurs between the aluminum and the rust. This

Did You Know on Instagram: "Oil spill cleanup is done using a combination of mechanical, chemical, and biological methods depending on the type, size, and location of the spill. The process usually starts with containment using floating barriers called booms to stop the spread of the oil, especially on water. Once contained, skimmers—specialized equipment like boats or machines—are used to remove the oil from the surface. In cases where mechanical removal isn’t sufficient, dispersants (chemicals
