Laser pens in school?

[TheFirstOfHerName]

The most recent school newsletter includes a reminder that laser pens are banned. Is this a thing now? I can see that it's not good if a pupil points a laser pen in the direction of someone's eye, but why would a teenager even have a laser pen, let alone feel the need to bring one to school?

We have several at home - cat toys, screen pointers etc

They would take them to school to point at the whiteboard and make pests of themselves

What do laser pens do?

well, they look like a pen but have a laser coming out of the end .....

used as pointers in presentations
used as cat toys
used to endanger aircraft and blind people

Think of all the things kids used to do by reflecting the sun off their watches only magnified...
