Knowledge Matrix on Instagram: "Natural rubber doesn’t start in a factory. It begins inside rubber trees (Hevea brasiliensis), where a milky fluid called latex flows through microscopic channels beneath the bark. To collect it, workers carefully make thin, angled cuts on the tree’s bark. The cut is shallow — deep enough to reach latex vessels, but gentle enough to keep the tree healthy for decades. Once cut, latex slowly drips out, guided by gravity into a small cup. This process is called tappi

HYPEWHIP on Instagram: "def a BMW driver Just as cars slide across asphalt to defy physics, high-performance boats can perform a liquid drift that trades burning rubber for massive walls of spray. Instead of breaking tire traction, a drifting boat relies on extreme momentum to displace water sideways, sliding through the fluid rather than just skimming on top of it. The technique flips standard automotive logic, as pilots usually steer into the turn rather than counter-steering, using directed t
