Here is a really stupid product called the Spyder III Pro Arctic manufactured by Wicked Lasers of Shanghai.
Just remember how the light saber rearranged Darth Maul.
I think the light saber book ends are a better buy for the kid's room.
May I quote its Web site? "Don't let the Arctic name fool you, this laser possesses the most burning capabilities of any portable laser in existence. That's why it's also the most dangerous laser ever created."
Oh, and "it will blind permanently and instantly and set fire quickly to skin and other body parts."
"People could very readily access this laser which could cause blindness. It could also start fires. ...
It has, however, been designed not to be too expensive. Together with shipping, the site suggested I pay a mere $227.96.
Working 'lightsaber' can set fire to your skin
