Go to your local hardware or home store and get a 1 liter can of acetone. You should be able to find it in the paint section. Do not use finger nail polish remover, okay?
While at the hardware/home store, also get a bag of epsom salt.
When you get home, pre-heat your oven to 200 degrees celcius. Take out a baking pan and cover with aluminum foil. Once the oven is pre-heated to 200 C., take a handful of epsom salt and spread it out over the foil. bake the epsom salt for 2 hours. Your final product should resemble that of ash.
Remove from oven and let cool. Once cool, take about two grams of the now anhydrous magnesium sulphate (formerly the epsom salt) and add it to your 1 liter of acetone. Shake well and filter into a seperate, non-plastic container. Discard filter. If your new container has an airtight lid, then your done. If not, simply pour your now anhydrous acetone back into it's original 1 liter can.
Now proceed with the directions......................................
