Make a pulse jet engine with a jam jar

Materials you will need:
- Drill and drill bit
- Rubbing Alcohol
- Jam jar
This Experiment Should Only be Performed Under the Supervision of a Professional
Drill a hole 1 cm in diameter through the lid of the jam jar.
Use a ruler to measure your hole. Make sure the hole isn't too small!
It's important to note that this project should only be completed under adult supervision since we're dealing with flammable materials. Since there's a good change the glass jar could break during this experiment, I recommend making a small tray using cardboard and tinfoil.
Unscrew the cap on the jar, take the rubbing alcohol and pour some into the bottom of the jar. You should pour until you have about 1 to 2 cm (approximately the width of your thumb) of isopropyl alcohol in the bottom of the jar.
Carefully shake the jar covering the top hole, making sure you coat the inside of the jar with the rubbing alcohol.
Take your lighter and carefully light the top of the jar.
Between tries, you should blow some fresh air into the jar to prime the next pulse.
Remember to be safe, and enjoy!
