Whether you’re camping or spending a day at the beach, bringing your own shower would be a neat trick. You can now do just that with the Road Shower 2. The product consists of a 57-inch-long aluminum tube that attaches to your vehicle’s roof rack and holds five gallons of water poured from a standard garden hose. The tube can be pressurized (up to 18 pounds per square inch) by attaching a bicycle pump or tire inflator to the relief valve. The attached 55-inch hose and nozzle releases the contents when needed (an LCD thermometer shows the water’s temperature). The Road Shower 2 sells for $300, including all necessary hardware, and is available at www.roadshower.com or www.stores.ebay.com/roadshowerllc.
