The people I have interviewed throughout this research process couldn’t quite categorise sugar. It seems to be neither animal, vegetable or mineral. It has got me thinking about sugar as an ‘archetype’ substance, an exemplar of the extraordinary in the everyday, and the magic in the material we’re made of. Through visual research I have begun to see a pattern emerge in the forms I encounter, a morphology of sugar.

Food and Drug Administration hazardous additives list in 2001. The efficacy of placebo ‘sugar-pills’ are a phenomenon that we still don’t completely understand. What is the relationship between belief and healing? How do properties that we project or imagine onto a substance translate into physiological effects?
People can and have been severely burned when that is done, even people standing some distance away. If you HAVE to do this demonstration, it would be best to be sure that any supply of flammable liquid is more than arms reach away, and better, in a different room, before you light the demonstration. There are three chemical reactions going on in this science demonstration. Don’t touch the carbon sugar snake until the flame has gone out and you have waited at least 10 minutes for it to cool down. Get an adult to pour roughly 20mL of methylated spirits, lighter fluid or ethanol into the indentation in the sand. Step 1/3 –Put 40g crystal sugar and 10g baking soda into the beaker and mix them together.
Using the lighter, light the mound and step back to watch the sugar snake develop. Shake the vial for 10 seconds to mix sugar and sodium bicarbonate. You must never taste any of the chemicals or products of the reactions that you work with, even if, in theory, it should be safe to do so. Perhaps you got an unexpected product from your reaction, or perhaps the starting chemicals contained impurities. In any case tasting your experiment could be very dangerous.
