Jello Science—aka Freaky Collagen

Jello uses gelatin, of course, for its bouncy texture, which you might not guess is made of animal bone and skin (specifically, a protein called collagen which also makes up a third of the human body.) When you make Jello, you have to boil it to break apart the collagen particles and cool it quickly to make it form a loose network of tangled proteins with water inside called a gel. The only difference between a pure liquid and a gel is that a gel has a few crosslinks between molecules here and there. But, it's not exactly a solid either because it's molecules are vibrating like a liquid.

Here are the possibilities:

Jello white house

Jello brain

Jello baseball

Jello neighborhood
