This is a clip from a recently surfaced video made for the Japanese government back in the 1990's. The animated short features the loveable Pluto-kun (Little Pluto, as in plutonium) who tells us that it's perfectly safe to drink water containing plutonium. Outrage from the international scientific community prompted officials to shelve it, and there hidden away on the shelf it remained until now.
I like my plutonium and water shaken, not stirred.
