This is a really simple piece once you have all the materials together.
A plastic anatomical reproduction of a skull
Tub of cream cheese and a knifeSmoked salmon
A taxidermy glass eye
Red food coloring
You can get the skulls on Ebay. Last year i purchased three "seconds" for about $30.
A note about the salmon - please buy wild Alaska salmon. The link goes to a friend's business - he gave me the salmon for this project. Alaska salmon fisheries are well regulated and sustainable. Stay clear of farmed fish which uses chemicals and artificial feeds. Farmed fish has been proven to not have the same health benefits of wild salmon.
