Homemade inexpensive Rockets

How to build real rockets

You will need three things and two tools:
  • You need matchsticks (about three packages)
  • You need cat litter (a handful of )
  • You need an old ballpen made of aluminium or hard plastic 
Tools needed:
  • drill 
  • muddler 


First step is to fill some catlitter into your empty ballpen and compress it very hard!


The catlitter is used to form your rocket's nozzle.
The second step: 
Take the matchsticks' heads and grind them to a fine powder.
Insert this powder carefully into the rocket:


Compress this powder, too. But be very gentle - i will ignite under too much pressure!!!

Now you have to close your rocket with catlitter:
To finish this rocketengine you have to drill a hole from the botten to about the halft of the matchstickpowder.The hot gases will escape throuh this hole and create thrust:


Now your rocket is ready to be fired! Attach some wings and put a rocket igniter into the hole:
READY FOR LIFTOFF!

  2. Take a matchstick, wrap a piece of aluminium foil around it - not too tight - and twist shut the end where the match head is, making the thing look like a cannon. Now light another match right under the enclosed match head, heating it to ignition. And pow!

    1. Use powder but be careful when pressing it together! It might blow up if you hit it too hard!
