Simple Stomp Rocket<\/h1>\n

Odds are you have these things in your home right now if you have done any plumbing recently.\u00a0 If not, the cost of materials is about $10 as of January 2019.\u00a0 \u00a0 That includes buying a full bottle of pop of sparkling water.\u00a0 \u00a0A 10 foot (3.5 metre) piece of 1\/2 inch (13 mm) PVC plumbing cost about $7.\u00a0 \u00a0Any plumbing store or general home improvement store will carry this.\u00a0 \u00a0You need one 90 degree elbow which retails for about $2.<\/p>\n

There are many plans for simple stomp rockets using a pop bottle and 1\/2 inch PVC plumbing pipe.\u00a0 Here is the simplest, and most elegant, version I have found.\u00a0 Special thanks to Peter Hopkinson who shared this idea with us through the BCAPT (British Columbia Association of Physics Teachers) when he was an instructor at VCC (Vancouver Community College, Vancouver, BC, Canada).<\/p>\n

Materials list:<\/strong><\/p>\n

10 foot piece of 1\/2 inch PVC pipe<\/p>\n

90 degree elbow for 1\/2 PVC pipe (1)<\/p>\n

empty pop bottle<\/p>\n

duct tape<\/p>\n

(optional) PVC glue<\/p>\n

Tools:\u00a0 <\/strong><\/p>\n

Pipe cutter or have the nice folks at the plumbing store cut the pipe for you.\u00a0 The lengths are not critical.<\/p>\n

Instructions:\u00a0<\/strong><\/p>\n

Cut the pipe into five pieces:\u00a0 5 feet or whatever height is comfortable for you to be able to blow into.\u00a0 \u00a0For safety it is better to be taller than most of your young students.\u00a0 \u00a0I am average height for a Canadian woman so I cut the long one about five feet long or 1.5 metres.\u00a0 \u00a0Cut three pieces that are 11.5 inches (29 cm) long to use as guides to make the rockets.\u00a0 The left over peice will be about 2 feet (60 cm) long.<\/p>\n

If you do not have a ruler with you then cut into four pieces = cut into half, cut one half into half, and then one of those halves into half again.\u00a0 Yes I had fun writing that.\u00a0 You will end up with four pieces about 5 feet long, 2 1\/2 feet long, 1 1\/4 feet long (2).<\/p>\n

Assembly:<\/strong><\/p>\n

Assemble as shown with the long and the medium pipes attached to the 90 degree elbow.\u00a0 A friction fit is all that is required.\u00a0 I used the stomp rocket shown above at an out door event for more than 6 hours.\u00a0 Hundreds of rockets were launched.\u00a0 I had to fit it back together just a few times.\u00a0 If that annoys you, use duct tape to hold it together better.<\/p>\n

(Optional) If you want to, use the PVC glue to glue everything together.\u00a0 Follow the instructions and make sure you are working in a well ventilated area.\u00a0 Personally, I have never bothered.<\/p>\n

Use:<\/strong><\/p>\n

Encourage rocket scientists to use one foot.\u00a0 If they stomp with both feet, or at the back of the bottle, odds are the bottle will break.\u00a0 I always bring along at least two bottles, but I have one bottle last for hundreds of launches.\u00a0 After the rocket has launched you blow the bottle back up by blowing down the tube.\u00a0 Make sure you sterilize it before and after use.<\/p>\n

Rockets<\/h1>\n

Wrap paper around one of the template lengths of PVC.\u00a0 Tap down one edge.\u00a0 Construction paper is best but it does not matter.\u00a0 If you make the rockets directly onto the PVC it can be difficult to get the paper rocket onto the launcher.<\/p>\n

Wrap an 8 1\/2 x 11 inch piece of paper around one of the short template tubes that have already have paper on it.\u00a0 Tape the long edge and one end of the rocket.\u00a0 Remove from the template, put on the rocket launcher and stomp away.<\/p>\n

The rest is up to you.\u00a0 If you add more mass to the nose area it tends to fly better.\u00a0 I use wine corks.\u00a0 \u00a0You can add nose cones, fins, etc.\u00a0 \u00a0This is where the artistry and the design cycle comes in.<\/p>\n
