I'm working at a nature camp this summer and the kids are all really great. I've been performing magic throughout the summer and some of the kids have really shown an interest in getting involved in magic. I want to help nourish that interest, so, in a week or two, I'm going to do an "Intro to Magic" course for the kids as an interest group (interest groups are something we do once a week where all the counselors pick an activity and kids from all different groups get to pick what they do for that block). I'm going to have kids ranging from 8-14, so I'm trying to get some ideas for some effects I could teach. I want them to be easy enough for the younger kids to understand, but cool enough that the older kids enjoy them. I'm not looking for anything major--no major sleight of hand or gimmicks. No major secrets--just some cool self working card tricks and a few other little things they can entertain their siblings and friends with. Any ideas you guys can contribute would be greatly appreciated. Thanks!
