Clip the garments peg onto the skewer, after which decrease the skewer into the glass, in order that the peg lies flat throughout the highest of the glass and the skewer is suspended, pointing downwards, and about midway into your sugar syrup. Be sure that the skewer doesn’t contact the facet of the glass.
  8. Put the glass someplace it will not be disturbed and go away it for a couple of days to permit the sugar crystals to construct.
  9. Verify again so your youngsters can see the crystals forming.
  10. When the sugar stick is prepared, eat it and inform your youngsters that the experiment didn’t work and that it’s essential strive it once more. 
  11. Simply kidding.
