Euclid discovers in scene 152 that the Funnel Stack can be launched, even when the Controller is not in proximity, by using a voice command.
The Stack collapses from 15 feet away. He checks Albert and then the Controller in his own hand.
Don't you have to be closer?
Euclid pushes the test further:
The Stack launches even though the Controller is nowhere near it. It has less power this time, only jumping 40 feet high.
