A chemical rocket

  1. Jun 15, 2010 #1
    I have an idea of creating a rocket using mentos and diet coke, but the failure rate is really high. I also tried reacting HCL + Mg in order to create pressurized Hydrogen Gas in the bottle, in order to make the rocket thrust upwards. I also used alka seltzer in creating a potential rocket, but to no avail.

    I would really appreciate if more ideas can be posted in this thread, of creating a rocket using some of the ordinary elements in the periodic table, or using things that are available (mentos, alka seltzer, etc).

    Look up "Matchstick Rockets." They are tiny rockets that use the pressurized gases of a burning match head to generate thrust.

    Dry ice is a very reliable method of producing a lot of gas quickly, if you want to keep a soda-bottle, non flame producing design.

    Wow, this takes me back. I remember making matchstick rockets with my friends 40+ years ago when I was a kid. We didn't have YouTube videos in those days, either, and I don't remember how we figured them out.

    Those where the times when we had no youtube, TV nor internet, but we had parents. I was shown how to make a matchstick rocket by my Dad.

    What on earth is a parent? Could I find it on the Google somewhere?
