I have a new project.

I’m going to buy a dead mouse for dissection or humanely put down a live one, remove select organs, inject into them a tad bit of formaldehyde, then dip them in polyurethane repeatedly until the organ is completely encased and has a hard polymer shell. Provided a I do it right, it should give a great view of the organ without worrying about sanitation, decomposition, or damaging it. Who wants one?
