Skimmers are often used in conjunction with booms. A skimmer is a device that collects and removes oil from the surface of the water. Skimmers can be towed, self-propelled, moored in river currents, or even used from shore. Many types of skimmers are available for use, depending on the kind of oil spilled and the weather conditions. Weir skimmers work like a dam. Oil flows over a wall and collects on the other side. Oleophilic (oil attracting) skimmers attract oil with belts, disks, or mop chains so you can just squeeze or scrape the oil out of them. Suction skimmers work like your household vacuum cleaner.

Sometime between 15 and 24 months, children take a large step in self-awareness. In an experiment known as the rouge test, mothers wiped a bit of rouge on the noses of their children and placed them in front of a mirror. Before 15 months, children look at the reflection and see a red spot on the nose in the mirror, but they don't realize that the red spot is on their own nose.
