Science experiment: Inflate a balloon with Coke and candy

Our supplies

 The kids have been begging for science experiments, so I found this one on pinterest. Basically, you combine a bunch of poison Coke & candy, and the reaction releases air and inflates the balloon. Fun times!









Directions:
1. Funnel Nerds and Pop Rocks into balloon.
2. Put balloon on the top of the coke bottle without allowing candy to fall into coke. (see video for that image)
3. Once the balloon is sealed, dump candy into soda and watch.

Before doing step 3, I asked the kids to guess what would happen when we put the candy into the soda. Their hypothesis: The balloon will inflate and then pop. After the experiment we recorded the result: The candy released the air in the soda and inflated the balloon. Despite the lack of explosion, the kids were still pretty happy with the experiment. 
After the experiment was over, Leif asked if they could taste the soda, so I had him guess if the soda would be fizzy or flat. He guessed flat, and was correct. Fortunately neither kid asked for more than a sip...and some candy, of course.
