FAMILY FUN

Here is a pretty experiment. Shape little pieces of chalk into ships, planing the bottoms evenly, and use matches for masts and funnels. Mark some of the ships with black ink and leave the others uncolored. Now put the rival fleets into a pan or plate, close to an imaginary line, and pour some vinegar between the forces. You will hear a sharp, .hissing sound, like escaping steam, and the ships will at once move forward, leaving tracks of foam in their wake. Their speed increases as they near the dividing line, and they come together with a crash and bump, striving to push one another out. Sometimes the battle is very exciting, the victorious side being the one with the most ships left in the centre.
