9/1/2023 0 Comments Glass weather indicatorOnce the glass pieces are heated, begin to shape them into the desired shape for the storm glass.Ħ. Begin to heat the glass pieces with the blowpipe, taking care to evenly heat all of the pieces.ĥ. Gather the pieces of colored glass from the kiln and arrange them into the desired design for the storm glass.Ĥ. Preheat the kiln to the desired temperature for glass-blowing.ģ. Gather the materials needed for the project, such as glass blowing tools, a kiln, colored glass pieces, a blowpipe, and a pair of safety goggles.Ģ. With a little patience and some basic supplies, you can make an attractive and useful storm glass of your own.ġ. Making your own storm glass is a fun and easy activity, and the results are sure to add a unique touch to your decor. You can also use the storm glass as a decorative piece in your home or office. The changes in the mixture will provide a unique barometer reading that can help you predict weather changes. Over time, the chemicals in the storm glass will respond to changes in the atmospheric pressure, resulting in changes in the appearance of the mixture.Ħ. The ideal temperature range is between 65 and 75 degrees Fahrenheit.ĥ. Place the storm glass in an area with consistent temperatures. Place the lid on the container and seal it tightly.Ĥ. Stir the mixture until all the ingredients are evenly distributed.ģ. Pour the distilled water into the glass container and add the Epsom salt, sugar, and ammonia. You will need a glass container with a lid, distilled water, two tablespoons of Epsom salts, two tablespoons of sugar, two tablespoons of ammonia, and a stirrer.Ģ. Here are the steps to make your own storm glass:ġ. Storm glass is a type of sealed glass container filled with a mixture of chemicals that reacts to changes in atmospheric pressure, making it an ideal barometer. When the weather's going to be bad the air pressure drops - and this makes our balloon bulge and the straw point downwards.Making your own storm glass can be a fun activity that also adds a unique decorative touch to any space. Because the balloon bulges or shrinks it also moves the taped straw up and down in front of the piece of card. When the air pressure outdoors is higher it presses in on the air in the jar more, and the balloon pulls inwards. When the air pressure outdoors becomes lower the air in the glass will expand and make the balloon bulge. By placing a balloon over the glass, some air has become trapped inside. What we've made is a device called a barometer, which can tell us if the weather will be dry or rainy based on atmospheric air pressure. When the straw points upwards the weather will be good, and when it points downwards the weather will be bad! So what's happening? Check the position of the straw over the next few days - draw a new line on the card for each type of weather and write what it is!. Mark a line on the card where the straw points, and write what the weather is right now (dry and sunny, raining and windy, etc) next to the line.Stick the piece of card to the wall behind the straw with blu-tack.The straw should stick out horizontally and parallel to the wall. Put the glass somewhere against a vertical surface like a wall somewhere where it won't get disturbed, like the back of a shelf.Believe it or not this is the main bit done! Hold the straw on top of the balloon so that one end is in the middle of the balloon and the other is past the edge of the glass.Cut the neck off of the balloon (ask an adult to help) and stretch the balloon over the glass."Window Drops" by Nate Steiner (Public Domain)ĭid you know you can tell what the weather will be without checking the forecast? In this experiment we make our own indoor weather-predicting device! Experiment
