Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials

1. Plastic water or pop bottle.
2. Power drill
3. Quarter inch bit
4. Aerosol deodorant or hairspray with butane or propane
5. Barbeque lighter

Step 2: Rocket Nozzle

Take the cap off the bottle and drill a quarter inch hole in the center. This will provide the exhaust flow passage for the rocket.

Step 3: Ignition

Spray a small amount of deodorant into the bottle and screw the cap on. Shake it up to mix the fuel with the oxygen in the air. Hold a lit barbeque lighter next to the nozzle to ignite the fuel and watch the rocket take off.

Step 4: Caution

Don't do this indoors or around people. Don't point the rocket at animals or anything that will break. Don't put anything flammable near the nozzle including your hands.

    this idea is very primitive, workable yes but dangerous to not only you but others too. So my suggestion? Please, incorporate a more sophisticated ignition system into your barbecue lighter method, so that you and your pals can stand further away at a safe distance to watch your rocket fly. Maybe, you can take apart your lighter, pick out the tiny little piezoelectric sparker and connect a long wire from the tiny sparker to the rocket's thruster nozzle. Then, if possible, build maybe a rail system to help aim your rocket

    But still , this a good try at making a rocket. I just hope no one gets hurt

    Someone should make a guide on DIY ballistics. I once saw a book about making these sorts of things, rockets, cannons, trebuchets.

    Are they still allowing users to make guides with admin permission? Or is it an admin only thing now?

    yeah after what rossag said i am NOT going to add this to the rocket ideas that i might do ....
    and anyway when you spray the aerosol or whatever into/onto something the burning somehow goes away......
    i tried to make a wd-40 rocket, the spay burns nice.....but when you spray onto/into summing then light=no fire=no thrust=me unhappy

    but it's a nice idea....could always try puncturing the bottle then lighting that

     i am sorry to say but it absolutely didnt work :(

    I did this indoors and pointed it at something breakable and put my hand near the nozzle. I got a really bad burn and had it bandaged up for 2 weeks.

    try using lighter butane or propane. also they work good attached to a hot wheel toy truck with a trailer attached.

    No photos? No launch video? BTW, these are seriously unpredictable - warn everybody nearby to get ready to run - I once nearly removed a colleague's ear with one of these, and he was sitting behind me.
