For this week's Mashable Vine Challenge, we want you to make a Vine video that creatively illustrates the theme light and dark.
You can experiment with natural or artificial light -- try playing around with colored light bulbs or black light for special effects. With this theme, the possibilities are endless, so we encourage you to be innovative and explore interesting light and dark settings to make your creation.
For our Vine example, we drew designs on a face with black light face paint. We then switched natural light for black light to expose the differences. For tips to create better Vine videos, check out our guide to Vine creation.
Tweet your Vine video by 6 p.m. E.T. on Tuesday, August 6 with the hashtag #LightAndDark for a chance to be featured in a follow-up post and have your creation revined. When choosing videos to feature, we look for a combination of creativity and technical merit. We can't wait to see your submissions!
