  Water Rocket Science Fair History

In the past, science fair projects that exhibited water rockets were not always available, due to their being messy to work with, their high unreliability and poor performance. My students use these pre-built water rocket kits. These water rockets demonstrate high reliability, safety and are reusable.

Now with pre-built kits available, you have the advantage of standing out from the other science fair entries and capturing your judges attention, by being one of the few exhibitions with a reliable water rocket. It's no wonder an elementary or high school science fair project such as this goes a long way to impressing the judges.

Water rockets as science fair project ideas never really became serious science fair experiments until about the year 2000. This was due to the availability of reliable pre-built water rocket kits.

The first written article explaining how to build a bottle water-rocket appeared in a US magazine, Mother Earth News (August 1983). However, commercially manufactured water rockets existed at least 35 years ago, so they've been around since the early 1940's.

It was only a few years ago, water rockets started getting patented. One of the early patents for a water rocket was by inventor Lonnie G. Johnson. Patent number 5,415,153 was issued on May 16, 1995 for a Pressurized air/water rocket and launcher.
