Compressed Air Rockets (Part2)

13 09 2008

So what this project is missing is two things. The first thing and most obvious is paper rockets. We’ll cover that later. Right now I wanted to describe how to make a detonation box or the ignition switch.

Most of the parts can be found at Radio Shack.  The part they may not have is the illuminate momentary push button, but they have plenty of buttons that aren’t illuminated.  The parts that are needed are detailed below:


9 Volt Battery

Single Pull Single Throw Switch

Momentary Push Button (LED illuminate if possible)

Binding Posts

Solderless Banana plugs

Altoids tin (or any other brand or some sort of enclosure)

This is what the final design will look like.

Note:  The binding posts are not shown in this picture.  That was thought up after the picture.  When I get the chance I will update the picture and take some pictures of the guts.


Compressed Air Rocketry (Part 1)

12 09 2008

Compressed Air Rocketry is well….just that rocketry using compressed air.  I got this idea from my friend Blakestradamus.  He has build these before and is quite the wizard.  He was going to build one for some cub scouts that were coming over to his house to investigate engineering careers.  I told him that I wanted to build one and that we could be two for twice the cost!  What a deal!

I’m going to try and detail everything that I did to assemble the Compressed Air Rocket Launch Pad.

All of the materials can be picked up at your local hardware store.  They should have all of these parts, but if not you can alter the design to the parts that are at your disposal.


2″ PVC Tubing  – about 5 feet.  This will be cut into 3 different pieces.

2″ PVC End Cap – 1

2″ 90° Elbow – 2

2″ coupler – 1

2″ to 1″ Reducer – 1

3/4″ slip / 1″ threaded joint – 2

1″ Sprinkler Valve – 1

1″ 90° Elbow / 1/2″ threaded  – 1

1/2″ thread/slip joint – 1

Compressor air hose connector – 1

Other materials not shown

PVC primer

PVC glue/cement

Non-Newtonian Fluid Fun!

I saw this a while back and I thought it was really interesting. If you haven’t played with cornstarch and water then you are missing out and you should drop what you are doing and go do it! DO IT!

Cornstarch and water looks like a liquid when you are moving it around, but when you touch, or poke it with your finger it act more like a solid. It’s pretty fun!

Ok, now that you went and played with cornstarch you can watch this video.

I know this is my project blog, but this guy, Karl Stanley, is so amazing that I have to post about him. Karl Stanley IS a MAD GENIUS and therefore gets to be heard on today’s blog. Karl has built his own personal submarine! He did it without any formal engineering school or training. That’s definitely genius! He has also logged in over 1000 personal dives in his submarine, and he did it all for about $20,000 dollars.

That makes me want to build my own submarine! It’s a pretty long article, but WELL worth the read!
