Make your own Crystals Follow FizzicsEd 150 Science Experiments: Comments 4 You Will Need: Adult help Three cups of table salt. 1L of water One Pencil 1 Paperclip A piece of string, cut to size. One strong plastic or Pyrex jar. Copyright Instruction 1 Boil the water with the help of an adult. Pour the water into the plastic jar. Do not use glass as it may break. 2 Add the salt one table spoon at a time. Allowing the salt to dissolve before you add more table spoons. Continue adding salt until you cannot dissolve anymore and it collects at the bottom of the jar. 3 Tie one end of the string around the pencil and the other end around the paperclip. Dangle the string into the saturated salt solution, so that the paperclip doesn’t touch the bottom of the jar or its sides. 4 Allow the jar to sit undisturbed for one week. Salt crystals should form at the top of the string 5 Get the Unit of Work on Mixtures here! How can we separate mixtures? What are the different techniques?

Cooling the solution down made it supersaturated, which is unstable. You should have found that the water travelled up the string through a process called capillary action, bringing the salt with it. As the water evaporated on the string, salt crystals were left behind. A supersaturated solution is a solution that has more material dissolved in it then it would normally allow. Find out more about capillary action on the external site USGS Water Science. Variables to test More on variables here Try using epsom salts or sugar instead of table salt. Do you get the same effect? Try cold vs. hot water as a comparison Does it matter which substrate that you form the crystals on? Learn more!

Sure thing! Just be careful of the hot sugar syrup. Compare these sugar crystals with the salt crystals. Reply
