School's out!!! Between barbeques and beaching, you'll have all this free time on your hands, so you might as well do a little DIY. Trash Amp's Mason Jar Speaker ($65) and, for the more tech savvy, the kit ($40) save plastics (which typically serve as speaker housing) from ending up in landfill. Hear sweet sounds from your mobile device, or use it as a practice guitar amp!
Because there's nothing as quintessentially outdoorsy as mason jars, the perfect vessels for jams and iced teas and capturing fireflies.
