Green Laser Pointer

Just imagine this: you are an expert in medical field and now it is your turn to show some special knowledge to your fellow students. In front of you is a body sample, with which you will give your lesson. What's more, the lesson is about the theory of how heart works. Actually, you can not touch the sample with your hand directly, then how will you express the knowledge clearly? The answer is a green laser pointer. If you are not familiar with the new thing, then in the next part of the article you will get some helpful information about this new high tech product.

A green laser pointer is a pointer which points some object with the green laser beam instead of a solid thing, for example, a teaching stick. As a result, the green laser pointer is often in the shape of a laser pointer pen. It just looks like a pen when you do not use it. When you use it to give lessons, the only thing you have got to do is to press the little button on the side of the pen. Then you will see a straight and bright beam shooting from the top of the pen. In the end, just control the beam to point to anything you want to. You will have a wonderful feeling in the process of using the pen because you see the convenience it brings to you.

It is cool, isn't it? It is not all about a green laser pen. We have other funny things about the little product. Since it generates laser beam, we can change the head of the pen to create something interesting. For example, we change a head which can create a beam in the shape of stars. And when we turn on the laser pointer, we see a little star on the cell. If we change it to a heart shape head, we will get a little heart on the cell. So it will not disappoint you only if you have interesting imagination. In other words, it becomes a toy, or a high tech toy, when you are not using it for giving lessons or holding meetings.

And this small thing is powered by two little batteries. By the way, it saves energy, so you do not worry about the frequency of changing batteries. Just enjoy using or playing it!
