Vinegar, Baking Soda, and...Balloon Eye Droppers?

Vinegar, Baking Soda, and...Balloon Eye Droppers
This is a very basic experiment: Watching the reaction of vinegar to baking soda. I thought this would be the perfect activity for little miss V, at age 2.5, to start her first science experiment! 
I did not have eyedroppers lying around my house for this project so I came up with a tool that is easier for a toddler to use, while providing the means to complete this experiment—balloons as eye droppers!
