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!
