The people at Wicked Lasers removed the laser from a Casio projector and put it into something that looks like a lightsaber prop. The Spyder III is not a toy, but is actually quite dangerous:
It will blind permanently and instantly and set fire quickly to skin and other body parts, use with extreme caution and only when using the included eye protection. Customers will be required to completely read and agree to our Class IV Laser Hazard Acknowledgment Form.
What could possibly go wrong?
