Here's a way to make cheap and easy epsom salt crystals in only hours. It's a fun way to observe science and engage in learning at the same time. The materials only cost about a dollar, making this a quick, clean, inexpensive, and simple. (That is if you don't already have them)

Step 1: What You Need

The only ingredients in making this experiment are 1/4 cup of epsom salt, a 1/4 cup of hot water, a fork, food coloring, a beaker or a bowl, and a refrigerator. These are easily obtainable objects that can be purchased almost anywhere.
table salt is sodium chloride and epsom salts are magnesium sulfate heptahydrate but the table salt will also form crystals give it a shot
Is this edible?
I would not try consuming this because it contains rock salt. it probably wouldn't be the best idea
thats cool i will have to do that <br>
Can you do this with normal table salt?
I'm not quite sure but that would be a great experiment.
Faster cooling = smaller crystals, cool them slow!<br> <br> <a href="http://www.instructables.com/id/How-to-grow-really-large-crystals/" rel="nofollow">http://www.instructables.com/id/How-to-grow-really-large-crystals/</a>
cool. Have you tried this yet?
Since I work in an organic chemistry laboratory, we could say that it's part of the daily routine(:<br> <br> <a href="http://labphoto.tumblr.com/tagged/portfolio" rel="nofollow">http://labphoto.tumblr.com/tagged/portfolio</a>
cool... again. Where do you work? I mean what's an &quot;organic&quot; chemistry lab?
