Cutting open a silk cocoon.

No commentary here, its just me cutting open a silkworm cocoon to show how tough it is (I have to use alot more force then I expected) and to see what it looks like inside (it contains the remains of the silkworm).

This silk cocoon can be bought from the normal school suppliers here in the UK.
