A laser is a light source that either emits or converts emitted light to coherent light. This means that the light from the laser is all going in the one direction, with the light waves in synch.
Lasers have many, many uses in science and medicine. Less powerful lasers are also commonly used in laser pointers for pointing out words on a screen or whiteboard, and used to make light shows in nightclubs, as seen in the picture.

Razors, also called shavers, are a hand-held device used for shaving. They have a handle and a covered razor blade that is designed to remove hair but not cut your skin. There are electric razors available as well as manual ones.
Schnauzers are dogs from Germany with a distinctive hairy moustache - 'schnauzer' is the German word for moustache. They are usually a salt-and-pepper colour, with white and black hairs mixed together. They were originally bred as a rat catcher and guard dog, but there are now three different size breeds - large, standard and miniature. They are friendly, loving dogs and are good with children. They are protective and make excellent guard dogs.
