Super easy. My kids loved doing this. I used wooden sticks I bought at a craft store. I treated them first by soaking in water then rolling them in sugar. I then used large canning jars, making sure sticks don't touch bottom of jar. I also let me kids make them flavored, and used food coloring. They came out better then anything store bought! I will have to remember to take photo's next time we do it , kids ate them so fast was not a chance to this time. :)
Kids loved watching the crystal form! We added food colour to this recipe for fun.
