To what extent does blender speed dissolve table salt + cold tap water? At home daily, I need to mix my table salt + COLD tap water. As "Marine salts dissolve faster and more thoroughly when added to circulating water," I "use a powerhead to speed up mixing time — my Vitamix 7500 blender.  Speed 10, ... (more) |

Why can these Single Vision lenses slow myopia for kids, but not adults? These WorldFamous companies advertise that their lenses can control myopia for kids, NOT adults. But none of these lenses are approved by FDA. I asked my optometrist why merely kids, not adults. But I could not understand his abstruse explanation at all! Can you please explain like I'm 5? >Essilor... (more) |

But please don't change the meaning of my post. You mistakenly edited my post to "I understood some points". No! I understood nothing! (more) |

| Question | — |
Optically, why are circular eyeglasses lenses better than rectangular? My optometrist said that round eyeglass lenses are OPTICALLY better than rectangular, particularly to correct myopia. He was NOT referring to fashion or style. I couldn't understand his explanation at all! I remembered merely some phrases about rectangular lenses like how they — 1. distort you... (more) |

| Question | — |
Why can someone observe light, even when the light fails to illume that someone? I never grokked the optics behind LightHouses and the WW2 poster below work. LightHouse beams are narrow and focussed. Doubtless, the light source can fail to illumine a seafarer or the enemy submarine. But then how can the seafarer or enemy sailors behold your light source? It counters intuiti... (more) |

Why do markers reflect light, even when the light source fails to illumine the space between the source and markers? Please see below screenshot of 15:59.The LED spot light (fastened to the front of the boat) illumines merely a few meters in front, and fails to illumine most of the water between the boat and the markers. So how can the LED still illumine the markers that I highlighted in orange? It counters in... (more) |

| Question | — |
Are lamps, with blistering light bulbs exposed and facing down on the user, dangersome? IKEA discontinued this NOVEMBER lamp in 2007, but I still use it. IKEA confirmed that they did not intend or design any cover or share with this lamp, and the light bulb is supposed to be exposed. But isn't this parlous? As you can see below, it uses a bizarrely shaped light bulb that heats up WAY... (more) |

Why did my roller luggage's wheels stop turning smoothly? Two weeks ago, my carry on worked perfectly. But last week the detachable wheels stopped rotating smoothly, when I tried to glide my carry on. The wheels budge JUST A TAD when you push them hard, but it should be EFFORT LESS! Here are two pictures. I see nothing jammed in the wheels. I ventilated... (more) |

Is it rational to freeze water bottles during colder nights, and place them in front of a fan during warmer days? 1. Is this advice correct? Are they alluding to Freezing Point Depression? Adding salt to tap water lowers the Crystalloid's freezing point. > Pour 3 tbsp (51 g) of salt into each of your 3 plastic water bottles. Use disposable plastic bottles for the easiest set-up and clean up. Pour 3 tablespoo... (more) |

Does folding glasses increase the probability of separating at the hinge? Please see the images below. I owned these Mykita John glasses for three years, which feels short for glasses to break! Every day, I fold them them before placing it on my night stand and going to bed. Today, when I unfolded them, the left temple just separated. Now I'm wondering if I folded my g... (more) |
