Lily, Please, please make sure that you have an adult help or supervise you. I'm an emergency room nurse, and I just finished a burn class. Let me tell you, things only have to be like 140 degrees to cause 3rd degree burns. We all usually heat our wax to 170-200, and wax is like oil. You know how when your skin gets oily it won't wash or wipe right off? You have to be SO VERY CAREFUL!!! I know 7th grade is pretty mature. My nephew is in the 7th grade, and I trust him to do a lot of stuff, but there are so many dangers out there that you guys don't see at your age. Please, please promise me that you'll get your mom or another adult to supervise you while you do this, or talk to your teacher and get another type of project. I chair the IRB (approval board) for a junior high science program, and I have to approve all of their experiments for their science fairs and things. I would really have a problem approving this without strict adult supervision..and even adults get burned all the time while making candles. One other thing...if you have smaller brothers or sisters, make SURE that they are no where around when you are working with hot wax. I'm telling you, accidents happen in the blink of an eye. If you and your mom decide to still do it, I hope you have fun and please, please be very, very careful!
