Warning: Ping-Pong balls are very flammable
In response to yesterdays post about the 8×16 LED matrix which used ping-pong balls as diffusers, Josh send this video and warns that the Ping-Pong balls are made of a very flammable material (nitro-cellulose). So If you are making a project using them as diffusers, keep in mind they catch fire very easily.
I had designed a kit that used ping-pong balls as LED diffusers for a nightlight, then I saw a demo of a flaming ping-pong ball at dorkbot. They’re sort of hard to light when intact, but as soon as you make a sharp corner by cutting them, an open flame catches really quickly.
Just something to keep in mind when installing an otherwise-awesome piece like this one. Don’t put it along critical fire-exit paths, because it will be its own little inferno in case of a fire.
