Encase a Light Emitting Diode, a small battery, and a light/heat sensing activation circuit in non-toxic, non-digestible translucent plastic. (I envision the diameter to be less than 2 mm).
When exposed to light or heat for the first time, the activation circuit turns on the LED, and keeps it on until
the battery runs out. This is long enough to use these little plastic balls in specialty drinks (think Orbitz), lollipops, or icing for "light" croissants.
Alternately, the "core" can be encased in a soft gel-type material to make sure it does not get broken while being consumed.
I'm not sure how to make this less toxic...

Thats the force it would be required to withstand. [Voice, Nov 07 2008]

BioToy: H2O glow

You're not supposed to drink it, but they did (wisely) test to make sure it's non-toxic. (To mice and rats, at least.) [jutta, Nov 07 2008, last modified Sep 04 2022]

For the same reason as sparkling candles, edible photographs, and Goldschlager... |

eatable toys for the kiddies, but anything weaker than a rock will be bitten through and anything stronger will break teeth unless you have some very strong gell container indeed. |

If the LEDs were really bright, there would be a nice soft, red glow from your abdomen after you'd swallowed the ball. |
|
| |
In places where raw sewage makes it to the sea, you would find a rather lovely light display. |
|
| |
This would act as a warning light-slick to locals and a shaming light-of-truth to jolt the relevant authorities into action. |
|
| |
...and enable lots of hilarious "Does the sun shine out of your arse, or what?" jokes. |
|
| |
To make it less toxic, go with some form of luciferase as a light source instead of electronics. |
|
| |
It might be a good way to get kids to swallow pills, it it could
be encased in medicine. |
|
| |
Or maybe that's not such a good idea. |

I've thought about a chemiluminescent reaction, but can't think of anything less toxic. (I've played with oxidizing luminol with Hydrogen Peroxide, but that's not exactly friendly. Perhaps there is edible fluorescent stuff out there--but that's not nearly as cool). Are fireflies toxic? |

Super bright LEDs inside the ears - now there is an IDEA. |
|
| |
//Are fireflies toxic?//
Yes, which is one reason they're rarely used in pastries. |
|
| |
Unless you intend to view [hippo's] sunshine, there's no need to have this stuff glow after consumption. You can make these things fluorescent, with a small external illuminator, or use fiber optics inside a drinking glass. |
