Rola Bola made of 27 inch long 2x8 pine, varnished
Life can be simple yet fun. Take the example of a Rola Bola, aka rolla bolla, rolo bolo, roly boly, balance board, rocker-roller board or bongo board. Whatever you call it, there is a board that allows you to stand shoulder width apart, a wooden stop board on the underside each end, and a rolling cylinder. You put the board on the cylinder and get on. Simple.
