    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.
