Excellent explanation, Jess!
The water wigglers are a fun little do-dad that is hard to describe. It is a hollow tube of liquid that will turn inside-out as the water flows downhill. If you hold them in your hand it will move along sort of like an ameoba (or octopus) moves. It is fun to let it crawl from one hand to the other, It is sold as a toy.
The space in the center is perfect for inserting a temp probe and the liquid surrounding the center warms and cools slower than the air around it. I don't know who first used it in an incubator, but it was a great idea!
