Sidewalk Chalk
Cost: $
Sidewalk chalk is a low-cost material that can be used to stripe very short-term demonstration project elements when fast removal is a concern. Use large chalk sticks to fill in a stencil or stripe a small area. Then, after fanning away excess chalk dust, apply hairspray and let dry for 3-4 minutes to seal the chalk. Chalk can also be used to communicate to users of the pop-up facilities by writing messages.
