Re: Glowing Hostas


Narda,

The easiest school demonstration of bioluminescence is probably to use
bacterial cultures.  They can be fun because the bacteria require oxygen to
glow, so the liquid cultures are aerated with an aquarium bubbler and only
the bubbles glow.  I would have to inquire as to who might have a culture.
Luminescent fungi can be brought into the classroom if it can be found.  The
most common type is Armilaria which can be found in some rotting wood in the
spring and summer.  This is the one most commonly called foxfire.  It takes
a very dark room to see the light and about 3 min for everyone's eyes to
adapt.
