- EXPLOSIVE MISSILES - Take a model rocket engine and scrape off the clay covering on the back until you expose the powder. You take your explosive(ex. co2) and place the fuse so it touches the powder. Now make sure they will not get separated in flight. You can do this buy simplily taking tape and taping them firmly together or take a paper towel tube and cut it down to size to rap around them snuggly together. These were made for the rocket launcher I have designed in file #007. These are very simple to make but can also be very deadly if shot at or around a person!! I do not recomend tring this unless you are around NOBODY!!!!! A really neat display for your rockets is making the paper match head I explained in another file and load that on the tip of the rocket. This makes a great display at night.....
