This DIY Bow Tie Defends Your Personal Space Bubble

By: Winona Dimeo-Ediger / August 16, 2013

The next time you hit up a formal event, repel chronic close-talkers and interrupt lingering hugs with this DIY bow tie. When someone gets within 19 inches of you (or whatever distance you prefer), the tie flashes four red lights until the person vacates your space bubble. I don’t typically have personal space issues, and I rarely wear bow ties, but damn, I totally want to make this and wear it to my next social event. [Makezine]
