Let's talk about lab water
We’re fairly obsessed with the wonders of water so we thought we’d share some exciting videos to prove just how truly magnificent the science of water really is.
If a tree falls in the woods and nobody hears it – does it make a sound? What about an iceberg being born? Surely there can’t be too many people who’ve heard that. Researchers recorded the sound of ice as it snapped, crackled and plopped into the ocean. The study was a re-‘sounding’ success, as it defined the underwater acoustic signatures of three different types of glacial calving – that’s iceberg birth to you and me!
The sweet (or salty if you prefer) sound of science. Physicists used high-speed imaging (2900 frames per second to be precise) to record corn kernels doing what they do best – popping of course! They detailed the motion of the popcorn jump, likening it to a one-legged break dancing move. The expansion of our beloved water vapor gives popcorn that familiar salivation-inducing popping sound, heard in cinemas across the land. Now that’s music to our ears (sorry about the corny pun).
It’s no secret that we love water, but not everyone is such a fan. Scientists in Australia observed water droplets accumulating on the backs of geckos and exploding off their skin. Turns out this could help prevent bacteria (who love water almost as much as we do) from thriving there.
What do knitting and NASA have in common? Well, astronauts use water droplets in orbit around a statically-charged knitting needle to illustrate satellites, which are kept in orbit by gravitational forces. Water droplets waltzing in space – we just couldn’t resist!
A study published by the Royal Society provides a clue as to how our tongues (and those of other land-dwellers) evolved from our aquatic ancestors. This video shows the mudskipper fish as it emerges with a mouth full of water, using it as a ‘hydrodynamic tongue,’ much to the detriment of its prey.
Nanoscale laser etching turns ordinary metals into super slick, hydrophobic masters. They repel water so well that water molecules literally bounce right off. This trumps common non-stick chemical coatings, such as polytetrafluoroethylene (more commonly known as Teflon), which aren’t even close on the hydrophobic scale and often peel off metal surfaces over time. Scientists at the University of Rochester say this technology could be useful for a range of applications, from solar panels to sanitation.
Well there you have it – feasting fish, gung-ho gecko skins, popcorn pirouettes, waltzing water droplets, iceberg births and not-so-sticky surfaces. We hope you enjoyed these ‘cinemaquatic’ treats as much as we did.
