    A water lens can be used for some interesting effects. For example, a little drop of water on the phone camera glass makes it work like a microscope. Of course, be careful since not all phone cameras are sealed enough to avoid the camera damage. The drop should be only in the middle of the glass.

    In the early 80s I did some straw based activities but I used powder to prevent the surface tension at the end of it

    Two questions: 1. Does it work with rubber or paper straws? 2. If you could make a straw so opaque that it prevents light from shining through, what effect would using the straw as a flashlight bring?

    I actually know a guy who poked his eye out looking through a straw like that. He didn’t really poke it out, but he messed up his eye pretty bad. He couldn’t uncover it for weeks and he said that it was by far the most painful thing he has ever experienced; his descriptions of the experience make it sound truly horrible. Please be careful if you are going to do this!

    So, does the lens effect only work while the straw is moving? What sort of effect happens when the straw is stationary? My brain is thinking that if the straw is not moving then the water would do the weird thing that it does and climb slightly up the sides of the straw forming a concave lens when it's not moving. Am I thinking about this wrong?

    well, the lens in your eye is cell based, which is water, but with a LOT of protein in solution (like hundreds of mgs/ml). This high protein concentration give the solution a high index of refraction, making a good lens material. The proteins are called crystallins, which are actually just house keeping proteins repurposed for lens development by evolution because they can exist at such high concentrations. Even more cool- the cells in the lens are super regularly packed, and the central cells get rid of all of their organelles, to increase optical clarity. Even MORE cool is that the refractive index isn't even uniform across, and the lens deforms ("accomodates") to focus on different distances. The visual system of vertebrates actually use two lens elements- the lens and the cornea, which is also super cool- how it arranges its collagen fibers to be clear, not opaque (like the sclera, which is white due to a different collagen arrangement). And even MORE cool is... oh. Wait. No one is even reading this. Derp.

    So, the surface tension causes the water surface to make a lens. As you move the straw up and down, it actually will cause the SURFACE of the water in the straw to rise and lower. This is because the bottom of the straw is going to be at a different pressure due to it's different depth, and will raise the waters surface in the straw at depth, and lower the surface of the water in the straw when the submerged end is shallow. The difference between the two surface levels will change the focal length of the 'lens' and cause more or less magnification.

    I had a really interesting experience once as a kid with this principle. I was floating upside down in the deepend of a pool. I exhaled and I have no idea how but a bubble got stuck perfectly over my eyes for a moment. My eyes were open and just for that moment I could see the bottom of the pool clearly, like wearing goggles, and beyond that magnified! I obviously couldn't stay terribly steady like this and the second Ii moved the bubble dislodged and floated to the surface and again the water was fuzzy looking with my bare eye. I wonder if you could recreate this experience somehow?

    Like anti matter, dark energy, is there anything like anti gravity (I am asking this question because in universe everything has something opposite to it). I'll thankful to you if you answer this question.

    Look up some of Nickolas Tesla's works, he theorized a form of this but it requires gravity to be a electromagnetic energy and not a force (extremely simplified), and also the theories associated with quantum gravity particle (Graviton) assuming gravity is a particle and has mass if observed. Both these theories contradict each other though if I understand then correctly.

    Crazy revolutionary clip For that you need: -A clip without plastic -Two neodinium magnets (with the same shape and strong) -A very thin thread and not elastic (better if it's long) Procedure: Put the thread around the clip (the part with one edge) and then rotate a lot the clip (around 150-200 times) put the clip close to the magnet 1 (and starts spining) pull it back and put it close to the magnet 2 (and starts spinning faster) do it whatever times you want and it will go so fast, it creats a sound. I don't know why that's happends (Sorry for my english)

    I'm not a physics expert by any stretch of the imagination. But withing the first 30 seconds I had figured out the effect through what I used to call 20 years ago, everyday miloisms! Suffice it to say, that even though I was never an A student for lack of ambition to be I always had a knack for understanding concepts and physical interactions both small scale and large-scale. I say all this to say where my appreciation and fascination for our shared joy comes from in regards to such small trivial observations.

    "Surface tension" creates a CONVEX lens as the straw is pushed down into the water; a CONCAVE lens is created as the straw is lifted. Alcohol has little or no surface tension based on its solution dilution(i.e. 50% rubbing alcohol vs 70% or 90%). A product by Shaklee called "Basic H" breaks down the surface tension of water without adding color or changing viscosity; improving the ability of water to permeate porous materials which makes it great as an additive to laundry. This product, Basic H, would negate the lensing effect displayed in this video. Cool, huh?

    Another, much drier, magnifier you can make is with your thumbs and forefingers. Put them together with a small opening between them. Get your fingers and eye really close to what you want to magnify, like letters in a book, and adjust the opening size. Voila, a magnifier.

    Why would the water form a convex surface? Wouldn't gravity and cohesive forces prevent that? What am I missing??

  62. putdownyourphone

    putdownyourphone5 bulan yang lalu

    Gravity is a relatively small force on something this size and the cohesive force or bond of the water molecules is stronger than the force gravity exerts, when the larger tube is used the overall surface flattens out due to gravity though at the very edge there will still be some small curvature due to cohesive forces.
