An apparatus including a first member, a second member, a third member, a first section, and, a second section. A first end of each of the first, the second, and the third member is fixed to the first section; and a second end, which opposes the first end of each of the first, the second, and the third member is fixed to the second section, in a manner such that the first, the second, and the third members are substantially parallel to each other, and the first and the second sections are substantially parallel to each other. The apparatus may be substantially smaller than an average adult person, and the apparatus may be configured so that the apparatus can be picked up by an average adult person gripping the first member, the second member, or the third member, and lifting the apparatus.
