In the spirit of Atomic Friday, we had to make it a challenge (red team vs. blue team as usual)! I carefully stuffed all the ingredients needed to complete each activity (with the exception of some ingredients that I obviously couldn't put into a balloon) into separate balloons (red balloons for the red team, and blue for the blue) and inflated them.
I briefly explained each activity, showing an example of the finished product and describing what was in each balloon. Then I spread all their balloons out on the floor and said "Go." Each team had to pop the balloons and complete the appropriate activity. The first team to complete all the activities was the winner. Here are some examples of the activities:
