This simple to build concrete outdoor bar with LED lights is constructed of 2x4 boards, fence pickets, and concrete. It's perfect for outdoor gatherings, barbecues, and parties. The first part of the project involves building the base for the concrete top. The second part involves building a mold for the concrete, creating knockouts, pouring concrete, and concrete finishing. LED lights shine through the clear acrylic coasters and bottom of the cooler to light up ice and drinks.
