today on size crystallization hey I'm Ryan I'm Adam and we're the side guys on today's episode we're gonna be showing you how to grow your own crystal recorder yes commander I shall obey who are you talking to no one crystallization is a natural or artificial process of forming eight solid crystalline precipitate out of a solution or melted substance the equipment unique to this experiment is a glass or beaker some fishermen eyed or thread a popsicle stick coffee filter and the only ingredients you're going to need are boiling water and alum alum is used for pickling and confided in your local grocery store so although we're not dealing with anything particularly dangerous today it's still a good idea to wear your lab coat and goggles to protect against spills and splashes the first step is to create some starter crystal seeds which will act as the starting point where our larger crystals will grow from begin by filling your glass half full of hot water next add a bunch of a linear water stir your solution until all the alum has been dissolved into the water continue to add small portions of alum to your water and mix it in until the alum stops dissolving in the water this will be apparent when some of the alum powder remains at the bottom of the glass place a paper towel or coffee filter over the glass and leave it in a room or cupboard where it won't be disturbed so it can cool let the glass sit until you have a large enough seed crystal at the bottom of the glass to tie a fishing line around this process can take a few hours or up to a few days to complete once you think you have a large enough seed crystal pour the liquid into a new Cup and remove the largest seed crystal take your seed crystal and tightly tie the fishing line around it be careful not to break your seed crystal tie the other end of your fishing line around the popsicle stick reheat your solution in a microwave then add all the extra crystals back into the hot water and mix it until all the crystals have been dissolved rest the popsicle stick across the top of the glass so that the crystal is in the middle of the liquid and not touching the bottom or any of the sides leave your crystal to grow a few days after a few days if there are crystals accumulating on the bottom of the glass remove your large crystal that is attached to the stick from your solution reheat your solution in the microwave and stir it until all the crystals have been dissolved you can add any extra alum you have at this stage to increase how large your crystal will grow repeat this step until there are no more crystals growing on the bottom of your glass once you're done growing your crystal remove it from the water let it dry and you will now have your very own alum crystal formation let's look at this experiment a little closer all liquids have a set solubility to a specific substance at room temperature some liquids have high solubilities others have low solubility x' solubility is the amount of a particular substance that can be dissolved into a specific liquid as the temperature of a liquid increases the solubility also increases in our experiment our waters temperature is much higher than room temperature this means that the amount of alum we can dissolve into the water is much greater than if the water was at room temperature this creates a supersaturated solution supersaturated solutions are solutions that have a higher solubility than what the liquid could normally handle when we leave our solution on the shelf the temperature of our solution slowly drops back down to room temperature as the temperature drops the maximum solubility of the water drops as well this leads to our solution releasing molecules of alum and these molecules form a solid precipitate as our solution gets cooler and cooler it releases more and more alum molecules these alum molecules accumulate at the bottom of our glass and create crystal formations the thing about alum molecules is that they would rather attach to an existing alum molecule or crystal formation rather than starting a new one this is proven when we add our seed crystal to our warm solution and as the solution cools the precipitated alum molecules attached to the seat crystal over and over again to create a large crystal formation this process is called crystallization the shape of the crystal is specific to the substance different substances like sugar or salt will create crystal formations of different shapes we will be exploring the shapes of different crystal substances and how to create them in future episodes so that was how to draw your own crystals at home using crystallization I hope you enjoyed it and remember to comment and subscribe down below on YouTube and make sure
