Glow in the Dark Sidewalk Chalk

Glow in the dark sidewalk chalk is a fun addition to an nighttime activity. You can use it to welcome youth to the event, write inspirational messages, or let your participants have a creative outlet.

Use it for any activity where there the chalk will be dark enough to glow. This is especially appropriate for any “light” themed youth ministry meeting. For example

• Let your light shine
• GLOW (God Lights Our Way)
• Light from darkness (creation)
• Jesus Christ Light of the World (salvation)
