And if you do what kind of food is it. Have you had experiences with that food and how do you avoid it. I also am doing a science pair project and I want to show a working demonstration on reactions of food allergies like sore throats, difficulty breathing, headaches, hives, constant coughs, wheezing, etc. Like for constant coughs I would have a tape recorder play coughs and wheezing noises. For tiredness, a balloon deflate as you loose your energy. What are some other ideas for the symptoms I explained. Like using balloons, recorders, etc. Thanks so much.
