I have a fridge\freezer with an ice maker. The automatic ice maker
storage got high and a single ice cube got placed behind the large storage tray, it has sat there for a while, but started getting smaller, now it is almost nothing. What causes this cube to get smaller in an environment that appears to stay the same? |

Some of the apartments I lived in was opposite the case, you had to defrost about every three months Reminds me spring time is a good time to pull out and defurr the the fridge. |

Before going over there for whatever occasion, I'd remind them to refill the trays. It would be very disappointing to go for dinner and find tiny little dehydrated cubes. nancy |

Ice Mites - Small, almost invisible creatures with constant teething problems. By eating the stray ice cubes that end up outside of the storage bin, they keep their gums numb. It's a survival instinct - if they didn't numb their gums, there would be this constant moaning from your freezer, resulting in detection and probable elimination. In desparate cases, when the ice cubes are removed by the human on a regular basis (resulting in few, if any, strays) the mites have been known to use their ice grabbing tenticles to create a small hole in freezer bags, allowing in just enough moisture for frost to form on the stored object. This gives them another source of ice to numb their gums. |

This gives them another source of ice to numb their gums. On this note, it's been observed that if you want to freeze meat or fish or shrimp and have it be just as good months later, a good technique is to put the food in a ziplock bag and then fill the bag full of water before zipping the bag shut. Freezer burn is due to sublimation of the water in the food, and by the method just described, the added water does the sublimating rather than the food. I tried this trick with same-day shrimp acquired in South Carolina in June, and I thawed the last 2-lb bag for dinner in January, and it tasted just like the shrimp cooked the first day. PD |

PD We get roadside roasted green chile every fall and there ends up being lots of great liquid. Twist the top making an ice seal by having wet hands when you twist it closed and a year later it still will have that great fresh roasted green chile flavor. |

Dan Yes. The explanation as to why your brother sees things that way is: he is a woo-woo. ***{I've seen those spikes myself. They rise up out of the centers of ice cubes. The likely reason is that the cube freezes from the outside in. That means there is a reservoir of liquid in the center of the cube as the outside freezes. Since water expands as it freezes, the liquid in the center gets squeezed tighter and tighter, and eventually pushes out through the point of least resistance. That point is usually at the top of the cube in the center. Only in that way can the pressure be relieved. Naturally, as water oozes out, it freezes around the edges of the opening so formed. Result: a little volcano type of structure arises there. That's how the spikes are formed. --MJ}*** ************************************************** *************** If I seem to be ignoring you, consider the possibility that you are in my killfile. --MJ |

Unfortunately, if the Arctic ice fields melt, then so do the Antarctic ice fields, though there may be some short-term (~10 year) anisotropy. And there is far more ice in the Antarctic than in the Arctic -- about 8 times as much. PD |

He used water displacement to prove that a piece of gold wasn't pure, by comparing its displacement to a piece of pure gold of the same weight. The only other way would have been to melt it down to measure the volume. -- aioe.org is home to cowards and terrorists Add this line to your news proxy nfilter.dat file * drop Path:*aioe.org!not-for-mail to drop all aioe.org traffic. http://improve-usenet.org/index.html Use any search engine other than Google till they stop polluting USENET with porn and junk commercial SPAM |

Ice is one of the few solids that is less dense in solid form than liquid form. And that's a good thing, otherwise, lakes and oceans would freeze from the bottom up. |

And sunk objects displace water equivalent to their volume. A boat full of iron ore has a density greater than that of water, else it would not sink. Accordingly, the volume it displaces when sunk is less than the volume it displaces when floating. The level in the canal goes down. |

Nope. The water level drops. In the boat, the iron ore displaces a volume of water equivalent to its weight. Once the ore sinks, it displaces only its own volume of water. As water is significantly less dense than iron ore, the water level goes down. You're confusing this puzzle with the one about floating ice cubes. Even Mr. Wizard got that one wrong |

Once the ore sinks, it displaces only its own volume of water. As water is significantly less dense than iron ore, the water level goes down. You're confusing this puzzle with the one about floating ice cubes. Even Mr. Wizard got that one wrong But if the ore is more dense, it would not float in the first place by itself. That is only a portion of the puzzle. The boat also had air pockets, lighter material in the hull, etc. If all of it sinks and air pockets remain, the level goes up. If you took iron ore by itself, it would sink right away and raise the level, but it never did float in the first place so it just moved water. . |
