Hi! I've got good news and bad news. The bad news is that my dad and I do not have a mini model finished and complete. The good news is that we have created different ways to build this. One way includes using PVC pipes as a stand, with an attachment for a garden hose and another attachment for air. This would not work for the real jet pack though, the five gallon one. Another way is to cut off the top part of another water bottle and put that on another water bottle (the small kind). This way I can make an airtight seal for both ends of the water bottle. You know; this project is sort of morphing into more of a bottle rocket kind of thing than a jet pack. Oh well. I like bottle rockets too.

Okay. Here's the news: my dad and I are going to build my mini model this weekend! We'll be using an empty Gatorade bottle (the bigger kind). My dad had an idea of using the cap (since it is already an airtight seal) as a way to make the spring loaded valve. Also, I had a thought that maybe my project will be the mini model and then after the school year's over I can continue it and make the bigger version. After all, I will have a much better understanding of what I'm supposed to do if i continue my project this way. I will have an update on the mini model on or around Monday, if all goes well. Talk to you then!

Hi! I've decided to make a mini jet pack. Instead of using a five gallon water jug, I'll just be using a regular water bottle
and I'm going to 3D print a pressure valve and an exhaust bell.
I am also going to measure the amount of water that goes the water bottle and find out the ratio for compressed air and water. The goal of this mini model is to learn a bit more about how this will work without trying anything too unsafe.
