We’ve recently added a nifty outdoor toy: The Water Rocket by 4M.
The concept is one you might have seen in smaller form: you pump up a model rocket that has a small amount of water inside. The pressure builds up a lot from your pumping and when you release the valve the high air pressure pushes the water out of the rocket. When that happens, good old Action/Reaction takes place to launch the rocket into the air.
This kit make a larger water rocket using a soda bottle and some parts to assemble it into a launchable rocket. The only thing not included is a bicycle pump – one that works a Presta valve (most do these days).
Once the rocket is assembled you pump it up and launch it up to 100 feet in the air! Please be sure to be outdoors.
This kit is a great entry into soda bottle water rocketry, don’t forget that you can buy a great instruction book to take things even further and make super soda bottle rockets!
We have a few new books in the store and they are mostly great books on how to do science projects on your own. Let’s start with Soda-Pop Rockets
Now of course the book is title ‘Soda-Pop Rockets’ so naturally they show a Water Cooler bottle being launched on the cover! But honestly the majority of the book does deal with using common soda bottles as water rockets. The books shows how to build a simple (and later more complex) rocket & launcher, with an old bike inner tube, a wire coat hanger, a bike pump and some tools. From there more advanced subjects like adding find, stacking bottles, parachute systems and more are covered. Other subjects covered are how to measure how high the rocket flies, and launching toy cars with rockets! This is a great book for the basics of water rocketry.
From water we go to the next books which covers (ta-da!) fire! The Practical Pyromaniac is the book for those fascinated by flame!
This is the book for people interested in safely experimenting with fire. Details are given on how to make a flame tube, candle-powered engines, and even make huge fireballs. All of the experiments are given in strong detail with an emphasis on safety (but still having fun and making cool fire effects!).
These books are great for folks who want the ‘old school’ do-it-yourself science experiments, pick up some copies today!
