My kids (ages 5 and 2) love making music by banging on pots and pans. So making instruments out of pie tins was right up their alley! As soon as we made a set, they pulled out a shaker and marched around the house in a mini-sized marching band. It was so cute I had to grab the video camera!
My five-year-old helped me cut some tape and attached the chopsticks right to the back of each pie tin. She loves all the fancy duct tape they have in the art store now.
My two-year-old was more about the glue and pom-poms. We got a system down: One would add glue and the other would stick a pom-pom.
