I decided to put together the last two instructables:http://www.instructables.com/id/EU4KXH7QP3ES9J6OQQ/http://www.instructables.com/id/E2OA96H1J9ES9J6PAN/
And came up with this cool idea that you may have seen in horror movies before.
The body part in glowing liquid....
First off you'll have to first do the other two instructables in order to make this interesting effect.
As a side note: The part placed in the water will slowly absorb the water and bloat. I've found that it usually takes 1.5-2 weeks for the part to bloat (depending on the size).
