The concept is simple. You call children to the front of the class, and ask them to choose a spoon, which they then stir into a cup of water. The water will either change colors, indicating which song the primary should sing, or will explode (bubbling up and spilling over the sides of the cup), which means the primary sings a song of the child's choosing. The children really seemed to enjoy the anticipation of finding the exploding cup(s).
- Place a drop of food coloring on each spoon.
- Cover each spoon with baking soda.
- Fill each cup with water except for the exploding cup(s), which should be filled with vinegar instead. (When the baking soda comes in contact with one of the cups of vinegar, it becomes an exploding cup, as the baking soda reacts to the vinegar.)
- You can make a note to yourself which colors go with which songs. I opted to write the songs on a piece of paper in colors that matched the food coloring. I wrote two songs for each color since I didn't know which spoon would end up in an exploding cup. Then, I let the child choose which of the songs of that color they wanted to sing.
This activity lasted the entire singing time, and was super fun.
I have seen this activity online on many other singing time blogs so I don't even know who to fairly credit. I will say that our stake primary chorister also shared this idea during our stake primary training a couple months ago (Megan T.), and said that she does this activity quarterly because it is so popular. In fact, I think she said it was her children's favorite singing time activity.
