It's hot this summer, but it's not that easy to cool down when you're on the go. You can't take an air conditioner with you, and a handheld fan will just tire you out, so you'll need to find more creative ways to cool down when you're on the go. One of these ways is a DIY solar-powered fan baseball cap.
A small solar cell is sewn into the crown of the hat which collects the sun's energy, and converts it into electricity that powers the small personal fan built into the front bill. This is a really cool solar idea; especially on the hottest, sunniest days when you must wear a hat to protect yourself from the solar rays.
You can now wear a solar-powered hat with a small cooling fan and stay cool all day!
