  • WOW New 11 Ways To Open Any Hard-To-Open Jar Lid

    We’ve all had the annoying moment when we just couldn’t open that jar. Lucky for you, if you watch my video, you’ll never again have to watch any other.

    My ways are guaranteed to help you no matter what situation you’re in, and no matter what kind of jar it is. Whether the jar is vacuum sealed or stuck with honey or something else, I’ve got you covered!

    You may always want to know the best way to do things. The best way depends on what is the problem. The problem could have different causes.

    If you just want to purchase your opener, here is the link: Opener

    If you could not open a jar, it could simply because you were turning it in the wrong direction, but assuming you didn’t make that mistake, there is only one reason why you can’t open it. That is, your force can’t overcome the resistance of the jar. For that, you may blame either the person or you may blame the jar. 🙂

    If you prefer to blame the person, there are 2 possibilities. You either have weak fingers or a weak wrist/arm.

    Weak fingers can’t apply sufficient force perpendicular to the surface to generate sufficient friction, thus your hand slips. To compensate for this, we can use many non-slip materials: rubber glove, leather glove, wide rubber band, balloon.

    To turn the lid, you should use your arm instead of your wrist to turn the lid, because your arm is much stronger, and wrists can be easily injured.

    If you feel that your weak wrist or arm is the problem, you can leverage your force by using tools with long handles. The longer the handle, the less force is needed. For example if you can extend the length of the pipe wrench, or the oil filter wrench, you will gain more power.

    If you think the jar is the problem, you need to investigate the 3 possibilities of what is causing the high resistance.
    The 3 causes are the vacuum seal, high friction on the threads and liner, or solidified food. You need to match the tools you have to solve each problem.

    Two solutions to break the vacuum: either prying or tapping.

    Prying: you may buy special tools, or you can use a beer bottle opener, a spoon, a butter knife or a screwdriver to poke around the jar’s perimeter so that you can introduce an air leak and break the vacuum.

    Tapping: You may use a wooden cooking utensil to whack the top of the lid. You need to whack it hard but not so hard that you break the glass. You hope it will break the vacuum as well as unstuck the lid. You can also use the back of a knife to whack as long as you’re careful.

    If a jar is vacuum sealed, then there is often a seal button, see here. If this button or the lid pops up, it means the vacuum is broken. If you have high friction on the threads, you may use a heating method. Reduce friction: Heating the metal lid will reduce the force needed because metal will expand more than glass.

    The heat source could be your stove, hot water, hair dryer or cigarette lighter.

    There are two common types of jar lid, one is continuous threaded where the jar and lid are both threaded in one continuous bead. It is similar to a nut and bolt. To open it, you need to turn at least 360 degree. Since the thread is long and gradual, you may potentially have a tighter seal, thus it may be harder to open it.

    The second type is lug or called twist-off type where the container has multiple threads and the lid has an equal number of lugs or tabs that grip the corresponding threads. You can see a few nubs here. To open it, typically you need to turn the lid less than 90 degree. This is easier to keep clean and free from sticky product.

    Sometimes a jar that has been opened before will still be tough to open if the contents are something sticky, like honey. When the lid is heated, the honey or other sticky substance should soften or melt, making it easier to twist open.

    Finally, if you have a jar of honey or something sticky, you can put some plastic wrap over the thread so that it will be easy for you to open it next time.

    Note: if you heat the jar, you may not heat too long because even though the vacuum has negative pressure, heating would generate vapor and thus may create positive pressure and explode.

  • How To Make A Free and Accurate Kitchen Scale

    youtube

    This kitchen scale took me only a few minutes to make. My invention uses a few commonly available materials and tools. It is free and pretty accurate. It is also durable and easy to use. To improve the accuracy, I have provided a few guidelines to help you to understand the usage and find the optimal accuracy for your own situation. Since all the parts used in making it can be used or shared with your other projects (the paint stick can be used as a ruler), it does not require any space to store it. I hope this video can inspire you to invent useful devices with things available to you. This kind of project will also nurture your kids’ creativity and future-proof their skills. If you have any tips, please leave a comment below.

    I will also show you how to make another very small scale that is hidden inside your shopping bag. This way you can do comparative shopping discretely. If you don’t have the time or the ability to make the first one, the rubber band scale is easier to make. But it does need more time to re-calibrate especially if you stretch it too much.

  • Various Different Ways to Make Yuanxiao (Tangyuan) or With Alternative Ingredients


    Today we are going to show you how to make Yuanxiao (or Tangyuan), sticky rice balls. Since you may or may not have the original Chinese cooking devices or ingredients, we are going to show you several ways to make Yuanxiao and some alternative ingredients.

    As candy canes are to Christmas, Yuanxiao dumplings are to Lantern Festival, the last day (which falls on the first full moon of the New Year) of the traditional Lunar New Year celebrations. Lantern Festival has also since commercialized into a sort of Chinese Valentine’s Day. The Chinese believe that the round shape of the Yuanxiao symbolizes family togetherness. By eating the rice balls, they will bring their family happiness and good luck in the New Year. For this reason, Yuanxiao are also served at Chinese weddings and any other occasion of family reunion.

    We had great success in making these – not even one filled rice ball broke open. The tastiest filling was the traditional black sesame. Other nuts and the chocolate filling tasted great as well. We tried adding avocado to some but did not particularly like the result.
