We have a company summer picnic coming up in a few weeks.  Since I am known as the maker in the office, I thought it might be cool to bring in a project.  “You know…for the kids”.  After flipping through some books, I found a Soda Bottle Water Rocket project in the Best of Make Book.  It turned out basically like the book but it is a bit unstable and finicky.  I am going to do some tweaks and then it will be ready for the picnic.  Good work Make.
