Laser fueled by human breath cuts glass tube in two


I love people who do wild scientific experiments in their homes, and anyone who creates a glass-cutting laser in their bedroom belongs on that list.

Carbon dioxide lasers are commonly used for cutting (think Goldfinger slicing James Bond in two), but where does a regular Joe get a cheap and reliable supply of carbon dioxide? Heck, we all emit the stuff when we exhale, so this laser is fueled by a balloon filled with human breath.
Watch as he uses it to cut a xenon glass lamp tube in half.
