One of the items I added for fun and was really excited to get in the mail the other day was a Soda Stream! We registered for the Soda Stream as well as 4 different flavors of syrup for the pop. As soon as we got it, we got it out and started using it. It was very simply and only took a couple minutes to figure out how to use it and to actually make the pop.
