Beamer Solar went to the Republican National Convention and gave Trump supporters free shirts that read: "Build A Wall." Not surprisingly, the shirts were a hit, with many Trump fans donning the Ts on the spot.

The shirts had a hidden secondary message  that only appeared when sunlight hit them. Each shirt wound up reading: "Build A Wall of Solar Panels on Your Roof," something Beamer Solar assumed Trump and fossil fuel supporters would be against. To the brand's surprise, the Trump fans were supportive of the cause.

"Let's build a sustainable future. It's something we can all agree on," closes the video, created by Arnold Worldwide.
