To oven-steam ribs, place ribs in a large baking pan, fill with about 1 inch of water, cover with aluminum foil and bake for about 50 minutes in a 350-degree oven. The recipe here includes instructions on how to boil ribs before grilling.
A rafter is one of a series of sloped structural members (beams) that extend from the ridge or hip to the wall plate, downslope perimeter or eave, and that are designed to support the roof deck and its associated loads. A pair of rafters is a couple.
A bubble raft is an array of soap bubbles that models the structure and dynamics of a real crystal consisting of atoms or ions. Most bubble rafts consist of a single layer and are therefore 2-dimensional; even so, they exhibit many of the same kinds of phenomena as seen in 3-dimensional crystals. The bubbles in a bubble raft are typically about 1 mm in diameter. If all the same size, the bubbles will self-assemble into a hexagonal array, the same as the arrangement of atoms in the {111} planes of a face centered cubic metal such as copper of aluminum.
