Flash-fire Sigils

1 can aerosol hairspray
1 lighter (preferrably the long kind used to light barbecues or pilot lights)
your imagination

Step One: Use the hairspray to draw something on the wall, ala graffiti.
Step Two: Use the lighter to apply flame to hairspray. It will go up in a brief, but lovely display, and if done right will take the shape of what you drew.

SAFETY PROCEDURES: Be careful of doing this near other flammable materials. Best done on a concrete or brick wall. The hairspray will drip down the wall, so keep flammable material away from the junction of the floor/ground and wall. Do NOT use a cigarette lighter.

NOTE: If you are confident in your throwing skills/have a fire extinguisher and first aid kit handy, matches may be substituted for a lighter.
