Since this was an Olympic year we decided to have a Backyard Olympic Birthday party for my 10 year old. We made the invitations as scrolls to look like the batons passed in track events and drew the Olympic rings on the top. The cake was a basic white rectangle again decorated with the 5 Olympic rings using decorating gel.(Super easy!) For entertainment the girls played crab soccer, had a javelin throw using feathers, relay race popping balloons, etc. Adding a twist or two to traditional events evened out the field and made for a lot of laughs.
