Amazon is selling the 50mw 532nm Astronomy Green Laser Pointer for just $10.50 (free shipping on orders of $25 or more), originally priced at $149.99. Its “beam can be seen up to 12 miles away at night” and is powered by two AAA batteries. Product page. Video of this laser pointer popping balloons after the break.

We ensure that every high power green laser pointer is hand calibrated and tested to output at least 50mw and thus offers the expected stunning power expected of a real constant wave green (532nm) laser pointer, much brighter to look at than a regular red laser pointer and always with a visible green beam.
