Ghost Rockets

This year, we still did the normal Halloween things, such as carving and decorating pumpkins and attending numerous fall festivals and pumpkin patches. Here's a picture. My oldest was creative and decided to do Grumpy Cat.

However, the girls really had blast with this activity that we did the week of Halloween. All you need for this activity is cornstarch, water, alka seltzer, and a container with a lid to put it in. We painted ours like a ghost.
You fill the container about 1/3 full of cornstarch, then add water until your container is about half way full. Stir the cornstarch and water together. We then broke up two tablets of alka seltzer and dropped them in the container. Finally, we put the lid on the container and then gave it about 30 seconds and then in flew! I really wish I would have taken a video of this. We enjoyed it so much that we did it over again. Each time when the container seemed to pop and fly, we all jumped. Beware though - it makes a mess. It splattered all over my face and clothes, while it will easily wash off - if you have somewhere to be, change into clothes you don't mind getting dirty.

Seeing our ghost fly was just a fun experiment and I talked about the chemical reaction that was happening with the built up pressure in the container to where it had to explode! I think the girls enjoyed this.
