You can now attach electronic circuits to cockroaches to control their movement.
First, place the cockroaches “in icy water to subdue them before sandpaper is used to remove the waxy coating on the shell of the insect’s head. An electrode connector and electrodes are then glued on to the insect’s body and a needle is used to poke a hole in their thorax in order to insert a wire.
Their antennae are then cut and electrodes are inserted. A circuit is attached to their backs, and signals are received through a mobile phone app allowing users to control the cockroaches’ movements to the left and to the right.” (http://www.bbc.co.uk/news/science-environment-24455141)
This attitude toward to life must be nurtured – the perfect gift for psychopathmas.
