  • Why do canned Sardines vary in prices?

    yea.. there are some that come with olive oil, less salt, extra omega 3, chilli , etc. But for the same number of fish(4pcs) in a Can (425grams) packing, prices could differ from $1.20 to $3.90.

    Question :

    1) Are there different spieces of sardines (like pink Salmon or Chinook salmon) that makes it cost more?

    2) Is price a good guide to nutritional value of canned Sardines? Let alone, all those : less salt, more spicy and olive oil gimmicks?

  • Why are movies getting narrower nowadays?

    I could understand the aspect ratio of 4:3 are for older CRT TVs and a 16:9 are for widescreen TVs, both ratios would fit prefectly into the Full screen of each monitor types. But why do movie makers nowadays make films in 2.39:1 ratio? It does not even fit into the FULL screen of the extra wide cinema screen, and some movies that I watch lately have black blank space on the top and bottom of the film. Are there any other wider screen ratio that that is not mention here and others are getting Full screen and we're not?

  • Magnifying glass to collect sun energy?

    I'm doing a school project on nature energy resources. I thought of using a magnifying glass to heat up water to steam which in turn drive some gears and crank shaft and thus spinning a small turbine. But somehow I just could get the water (about 500ml) to heat up fast enough. Is there any other material I could used to collect and concentrate more sun energy to boil sme water?

  • Find it hard to explain, can someone help?

    A foreign friend asked if it's right (grammatically) to say "No matter what I do, I'll get it right". I find something amiss here but just couldn't explain what's wrong. "no matter" somehow negates it to be right.... or was it a double negative grammar that's all so confusing?

    I told him it would be better to say " I'll do whatever it takes to do it right"... but the big question is what wrong with his technically?
