Rockets and failing parachutes (Made by me)

 Hej hej,

I have mode some test parachutes for the Wonder project. What's the Wonder project you ask? Well it's a project where you make your own rockets and once done you can launch your very own rocket! We were currently in the process of learning about parachutes and making them by scratch using only the materials we were given. I will give you the step by step program on how I made my parachute

1. I made a circle prototype using newspaper, a cloth rag and string. It was my start off idea and I attached a pencil to it that managed to float for about 1 second instead plummeting to the ground, so it was my base for the finished project.

2. I made a bigger version of the prototype and added a little bit more of tape, i thought it did good with the pencil so on went the two cogs that we had to fly down and the parachute folded on itself.

3.I then added some paper towels for more strength but it didn't work too well so I brainstormed some more ideas.

4. I had the idea of putting some string and taping it on to the places where the parachute was folding in and it stopped folding in on itself when falling, so now there's an x of string on the top of the chute that allows it to fall.

5. to hold the cogs in place one of my team members decided to incase the two hex nuts in layers of tape and material which added safety and weight, too much weight.

The final outcome looks like this - 

You can see the tape, the nut holder, the materials, and the string.

Overall from roughly 3-5 meter height it flew 2.3 seconds which isn't too bad might I say myself.

OK byebye

  1. Hey Sam, I really like your parachute, You should really try this again adn see what you can improve on. I would like to know what you're group did to come up with this idea. Also, I would like to know what your test time is?
    Keep on doing the blog posts,
