You Will Need:
1/4 cup (container)of Epsom Salts (Magnesium Sufate)

Step 2: Water Boiling

1)Boil the Water in a microwave, kettle or stove, when it is boiled, add epsom salts and food colouring(optional)

    table salt is not the same thing as Epsom salt. Table salt: NaCl; Epsom salt: MgSO4. Due to the nature of its elements and their bonds, table salt will not form crystals such as these.

    Water most certainly will boil in a microwave. The superheating issue only really comes into play if the container lacks enough nucleation sites to get a good boil going. I boil water nearly every day in the microwave, 2 cups/500ml will boil in my microwave in approximately 3 min give or take 10 seconds. That said, I have used very very clean erlenmeyer flasks to superheat water and cause a crazy eruption upon agitation in a microwave too. The erlenmeyer works really good for this due to the narrow neck allowing a slightly higher pressure in the vessel. It's pretty damn cool really, but also dangerous you can burn yourself quite badly if you are not very careful

    Try www.camdengrey.com They offer lots of raw materials such as epsom salt, citric acid, lye, oils, waxes. They offer lots of products for soapmakers or crafters.

    How do you get your crystals to grow tall? I tried this as an arts & crafts project at work, and all of our crystals stayed quite flat to the bottom of the bowl. Also, are they supposed to break apart if you touch them? Many thanks for any advice.

    it should be available at your supermarket or local pharmacy. It would normally be sold as "epsom salts" though (like he says at the start) shouldn't be very expensive to do as well :)

    Maybe some more pictures would be nice. The instructable just seems empty the way it is.
