What your looking for is formaldehyde or formalin but this stuff is toxic and hazardous. I'm not sure if you can purchase this stuff as a private individual. Being toxic I'msureitsnot safe enoughto have kids handle.

Alternative, find the most concentratedbottle of rubbing alcohol. This should work well enough for a classroom setting. I'm not sure about long term preservation though. Try it first and let us know with some pics.

Good luck.

Use formalin ..... it's a solution of formaldehyde with stabilizers and preserves better than alcohol which dries the specimen. Go to local hospital and they'll provide it. It's the standard tissue preservative.
